Prior to this change element's i18n attributes like "i18n-title" were processed after "i18n" ones that placed "i18n" and "i18nAttributes" instructions in wrong order, thus "i18nAttributes" failed to target its host element at runtime. This change updates processing order and puts "i18nAttributes" instructions in front of "i18n" ones to resolve the problem.

Up until this point, all static attribute values (things like `title` and `id`)
defined within the `host` are of a Component/Directive definition were
generated into a `def.attributes` array and then processed at runtime.
This design decision does not lend itself well to tree-shaking and is
inconsistent with other static values such as styles and classes.
This fix ensures that all static attribute values (attributes, classes,
and styles) that exist within a host definition for components and
directives are all assigned via the `elementHostAttrs` instruction.
```
// before
defineDirective({
...
attributes: ['title', 'my title']
...
})
//now
defineDirective({
...
hostBindings: function() {
if (create) {
elementHostAttrs(..., ['title', 'my-title']);
}
...
}
...
})

This update aligns Ivy behavior with ViewEngine related to empty bindings (for example <div [someProp]></div>): empty bindings are ignored.

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.

Prior to this change Component decorator was resolving `encapsulation` value a bit incorrectly, which resulted in `encapsulation: NaN` in compiled code. Now we resolve the value as Enum memeber and throw if it's not the case. As a part of this update, the `changeDetection` field handling is also added, the resolution logic is the same as the one used for `encapsulation` field.

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).

The pure functions in host bindings change was merged after the change in
host binding instructions, so it had a new test that wasn't yet updated
with the new generated code. This commit updates the new test.
PR Close#27605
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.

PR #27404 introduced additional test case to make sure we generate `elementStyling` instructions with proper set of arguments (first argument was missing in some cases). It looks like that PR was created before we updated host vars count calculation and the `allocHostVars` becomes unnecessary in the test cases introduced in PR #27404. This commit actualizes this test to get rid of unnecessary `allocHostVars` instruction.

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 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.

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

When generating the 'directives:' property of ngComponentDef, ngtsc
needs to be conscious of declaration order. If a directive being
written into the array is declarated after the component currently
being compiled, then the entire directives array needs to be wrapped
in a closure.
This commit fixes ngtsc to pay attention to such ordering issues
within directives arrays.

This commit creates an API for factory functions which allows them
to be inherited from one another. To do so, it differentiates between
the factory function as a wrapper for a constructor and the factory
function in ngInjectableDefs which is determined by a default
provider.
The new form is:
factory: (t?) => new (t || SomeType)(inject(Dep1), inject(Dep2))
The 't' parameter allows for constructor inheritance. A subclass with
no declared constructor inherits its constructor from the superclass.
With the 't' parameter, a subclass can call the superclass' factory
function and use it to create an instance of the subclass.
For @Injectables with configured providers, the factory function is
of the form:
factory: (t?) => t ? constructorInject(t) : provider();
where constructorInject(t) creates an instance of 't' using the
naturally declared constructor of the type, and where provider()
creates an instance of the base type using the special declared
provider on @Injectable.
