Libraries that create components dynamically using component factories,
such as `@angular/upgrade` need to pass blocks of projected content
through to the `ComponentFactory.create()` method. These blocks
are extracted from the content by matching CSS selectors defined in
`<ng-content select="..">` tags found in the component's template.
The Angular compiler collects these CSS selectors when compiling a component's
template, and exposes them via the `ComponentFactory.ngContentSelectors`
property.
This change ensures that this property is filled correctly when the
component factory is created by compiling a component with the Ivy engine.

exportAs in @Directive metadata supports multiple values, separated by
commas. Previously it was treated as a single value string.
This commit modifies the compiler to understand that exportAs is a
string[]. It stops short of carrying the multiple values through to the
runtime. Instead, it only emits the first one. A future commit will modify
the runtime to accept all the values.

This commit adds sanitization for `elementProperty` and `elementAttribute` instructions used in `hostBindings` function, similar to what we already have in the `template` function. Main difference is the fact that for some attributes (like "href" and "src") we can't define which SecurityContext they belong to (URL vs RESOURCE_URL) in Compiler, since information in Directive selector may not be enough to calculate it. In order to resolve the problem, Compiler injects slightly different sanitization function which detects proper Security Context at runtime.

Previously, there could be identical template/listener function names
for a component's template, if it had multiple similarly structured
nested sub-templates or listeners.
This resulted in build errors:
`Identifier '<SOME_IDENTIFIER>' has already been declared`
This commit fixes this by ensuring that the template index is included
in the `contextName` passed to the `TemplateDefinitionBuilder`
responsible for processing nested sub-templates.
Similarly, the template or element index is included in the listener
names.

Some of the animation tests have been failing because animation gets
triggered multiple times. The reason for this is that the compiler was
generating static attribute bindings in addition to dynamic bindings.
This created multiple writes to the animation render which failed the
tests.

Previously ivy code generation was emmiting the projectionDef instruction in
a template where the <ng-content> tag was found. This code generation logic was
incorrect since the ivy runtime expects the projectionDef instruction to be present
in the main template only.
This PR ammends the code generation logic so that the projectionDef instruction is
emmitedin the main template only.

Prior to this change, we were unable to match directives using `ng-template` tags (for example the following selector would not work even though there might be some <ng-template>s in a template: `ng-template[directiveA]`. As a result, that broke some components that relies on such selectors to work. In order to resolve the problem, we now pass tag name to the `template` instruction (where we passed `null` before) and this tag name is used for matching at runtime. This update should also help support projecting containers, because the tag name is required to properly match such elements.

Closure Compiler doesn't allow non-goo.getMsg const names to start with `MSG_`, so we should use different prefix for const that references a result of the `i18nPostprocess` fn invocation. With this update we also append file-based prefix to i18n constants (via $$ postfix) to ensure the names are unique across codebase of a project (otherwise it might lead to errors while compiling a project with Closure Compiler).

Previously in Ivy, host bindings did not work if they shared a public name
with an Input because they used the `elementProperty` instruction as is.
This instruction was originally built for inside component templates, so it
would either set a directive input OR a native property. This is the
correct behavior for inside a template, but for host bindings, we always
want the native properties to be set regardless of the presence of an Input.
This change adds an extra argument to `elementProperty` so we can tell it to
ignore directive inputs and only set native properties (if it is in the
context of a host binding).

Prior to this update, we always returned the number of host vars defined in @Component definition as a value for `allocatePureFunctionsSlot` callback in ValueConverter. As a result, pure function arguments were not accounted for, thus leasing to incorrect slot offsets in `pureFunction` calls. Now we update and return total # of host vars, so the offsets are defined correctly.

Prior to this change, animation event names were treated as a regular event names, stripping `@` symbol and event phase. As a result, event listeners were not invoked during animations. Now animation event name is formatted as needed and the necessary callbacks are invoked.

While generating attributes for `projection` instruction, we checked whether attribute name is equal to 'select' in lower case. However in other cases we treat 'select' attribute name as case-insensitive. This PR makes 'select' attribute consistently case-insensitive.

Prior to this change, animation properties were defined as element attributes, which caused errors at runtime. Now all animation-related attributes are defined as element properties.

Analogously to directives, the `ngInjectableDef` field in .d.ts files is

The logic that generates first argument for the `elementStyling` instruction was missing the check that directive expression is specified. As a result, in some cases first argument was not added, thus making function invocation incorrect. Now the presence of directive expression is taken into account and the `null` expression is generated as needed.

The problem was caused by missing `allocateBindingSlots` that led to incorrect # of vars defined for components and as a result, causing errors at runtime. Now all `bind` operation are accounted for and the number of `vars` is correct.

The problem was caused by the self-closing i18n instruction that was generated in case we have styling instructions defined for a component. As a result, that caused problems at runtime. This update adds extra check to avoid creating self-closing i18n instructions (create i18nStart and i18nEnd instructions instead) when styling instructions are present.

Previously the concept of multiple directives with the same selector was
not supported by ngtsc. This is due to the treatment of directives for a
component as a Map from selector to the directive, which is an erroneous
representation.
Now the directives for a component are stored as an array which supports
multiple directives with the same selector.
Testing strategy: a new ngtsc_spec test asserts that multiple directives
with the same selector are matched on an element.

This commit introduces the setClassMetadata() private function, which
adds metadata to a type in a way that can be accessed via Angular's
ReflectionCapabilities. Currently, it writes to static fields as if
the metadata being added was downleveled from decorators by tsickle.
The plan is for ngtsc to emit code which calls this function, passing
metadata on to the runtime for testing purposes. Calls to this function
would then be tree-shaken away for production bundles.
Testing strategy: proper operation of this function will be an integral
part of TestBed metadata overriding. Angular core tests will fail if this
is broken.
PR Close#26860
Uglify and other tree-shakers attempt to determine if the invocation
of a function is side-effectful, and remove it if so (and the result
is unused). A /*@__PURE__*/ annotation on the call site can be used
to hint to the optimizer that the invocation has no side effects and
is safe to tree-shake away.
This commit adds a 'pure' flag to the output AST function call node,
which can be used to signal to downstream emitters that a pure
annotation should be added. It also modifies ngtsc's emitter to
emit an Uglify pure annotation when this flag is set.
Testing strategy: this will be tested via its consumers, by asserting
that pure functions are translated with the correct comment.

We are close enough to blacklist a few test targets, rather than whitelist targets to run...
Because bazel rules can be composed of other rules that don't inherit tags automatically,
I had to explicitly mark all of our ts_library and ng_module targes with "ivy-local" and
"ivy-jit" tags so that we can create a query that excludes all fixme- tagged targets even
if those targets are composed of other targets that don't inherit this tag.
This is the updated overview of ivy related bazel tags:
- ivy-only: target that builds or runs only under ivy
- fixme-ivy-jit: target that doesn't yet build or run under ivy with --compile=jit
- fixme-ivy-local: target that doesn't yet build or run under ivy with --compile=local
- no-ivy-jit: target that is not intended to build or run under ivy with --compile=jit
- no-ivy-local: target that is not intended to build or run under ivy with --compile=local

Previously in Ivy, metadata for directives/components/modules/etc was
carried in .d.ts files inside type information encoded on the
DirectiveDef, ComponentDef, NgModuleDef, etc types of Ivy definition
fields. This works well, but has the side effect of complicating Ivy's
runtime code as these extra generic type parameters had to be specified
as <any> throughout the codebase. *DefInternal types were introduced
previously to mitigate this issue, but that's the wrong way to solve
the problem.
This commit returns *Def types to their original form, with no metadata
attached. Instead, new *DefWithMeta types are introduced that alias the
plain definition types and add extra generic parameters. This way the
only code that needs to deal with the extra metadata parameters is the
compiler code that reads and writes them - the existence of this metadata
is transparent to the runtime, as it should be.

This commit introduces the "t2" API, which processes parsed template ASTs
and performs a number of functions such as binding (the process of
semantically interpreting cross-references within the template) and
directive matching. The API is modeled on TypeScript's TypeChecker API,
with oracle methods that give access to collected metadata.
This work is a prerequisite for the upcoming template type-checking
functionality, and will also become the basis for a refactored
TemplateDefinitionBuilder.

Upcoming implementation work for template type-checking will need to reuse the
code which matches directives inside a template, so this refactor commit moves
