This patch introduces the `printTable()` and `printSources()`
methods to `DebugStylingContext` which can be used via the
`window.ng.getDebugNode` helpers when debugging an application.

Injectable defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.
This commit adds the prefix and shortens the name from
ngInjectableDef to "prov" (for "provider", since injector defs
are known as "inj"). This is because property names cannot
be minified by Uglify without turning on property mangling
(which most apps have turned off) and are thus size-sensitive.

Prior to this commit, Ivy runtime asserted that a given element is an instance of a DOM node. These asserts may not be correct in case custom renderer is used, which operates objects with a shape different than DOM nodes. This commit updates the code to avoid the mentioned checks in case procedural renderer is used.

This patch enables a styling debug instance (which is apart of the
`debugNode.styles` or `debugNode.classes` data structures) to expose
its context value so that it can be easily debugged.
PR Close#32856
Prior to this fix, whenever a style or class binding is present, the
binding application process would require an instance of `TStylingContext`
to be built regardless of whether or not any binding resolution is needed
(just so that it knows whether or not there are any collisions).
This check is, however, unnecessary because if (and only if) there
are directives present on the element then are collisions possible.
This patch removes the need for style/class bindings to register
themselves on to a `TStylingContext` if there are no directives and
present on an element. This means that all map and prop-based
style/class bindings are applied as soon as bindings are updated on
an element.

A PR that updates one of the benchmarks and another one that changes the signature for `elementStart` got in around the same time which is causing a compilation error. These changes fix the error.
PR Close#33067
Currently Ivy stores the element attributes into an array above the component def and passes it into the relevant instructions, however the problem is that upon minification the array will get a unique name which won't compress very well. These changes move the attributes array into the component def and pass in the index into the instructions instead.
Before:
```
const _c0 = ['foo', 'bar'];
SomeComp.ngComponentDef = defineComponent({
template: function() {
element(0, 'div', _c0);
}
});
```
After:
```
SomeComp.ngComponentDef = defineComponent({
consts: [['foo', 'bar']],
template: function() {
element(0, 'div', 0);
}
});
```
A couple of cases that this PR doesn't handle:
* Template references are still in a separate array.
* i18n attributes are still in a separate array.

In View Engine, animation metadata could occur in nested arrays which
would be flattened in the compiler. When compiling a component for Ivy
however, the compiler no longer statically evaluates a component's
animation metadata and is therefore unable to flatten it statically.
This resulted in an issue to find animations at runtime, as the metadata
was incorrectly registered with the animation engine.
Although it would be possible to statically evaluate the animation
metadata in ngtsc, doing so would prevent reusable animations exported
from libraries from being usable as ngtsc's partial evaluator is unable
to read values inside libraries. This is unlike ngc's usage of static
symbols represented in a library's `.metadata.json`, which explains how
the View Engine compiler is able to flatten the animation metadata
statically.
As an alternative solution, the metadata flattening is now done in the
runtime during the registration of the animation metadata with the
animation engine.

Prior to this change, ng-reflect properties were not created in case an attribute was marked as translatable (for ex. `i18n-title`). This commit adds the logic to generate ng-reflect for such cases.
PR Close#32989
In an attempt to be compatible with previous translation files
the Angular compiler was generating instructions that always
included the message id. This was because it was not possible
to accurately re-generate the id from the calls to `$localize()` alone.
In line with https://hackmd.io/EQF4_-atSXK4XWg8eAha2g this
commit changes the compiler so that it only renders ids if they are
"custom" ones provided by the template author.
NOTE:
When translating messages generated by the Angular compiler
from i18n tags in templates, the `$localize.translate()` function
will compute message ids, if no custom id is provided, using a
common digest function that only relies upon the information
available in the `$localize()` calls.
This computed message id will not be the same as the message
ids stored in legacy translation files. Such files will need to be
migrated to use the new common digest function.
This only affects developers who have been trialling `$localize`, have
been calling `loadTranslations()`, and are not exclusively using custom
ids in their templates.

With #31953 we moved the factories for components, directives and pipes into a new field called `ngFactoryDef`, however I decided not to do it for injectables, because they needed some extra logic. These changes set up the `ngFactoryDef` for injectables as well.
For reference, the extra logic mentioned above is that for injectables we have two code paths:
1. For injectables that don't configure how they should be instantiated, we create a `factory` that proxies to `ngFactoryDef`:
```
// Source
@Injectable()
class Service {}
// Output
class Service {
static ngInjectableDef = defineInjectable({
factory: () => Service.ngFactoryFn(),
});
static ngFactoryFn: (t) => new (t || Service)();
}
```
2. For injectables that do configure how they're created, we keep the `ngFactoryDef` and generate the factory based on the metadata:
```
// Source
@Injectable({
useValue: DEFAULT_IMPL,
})
class Service {}
// Output
export class Service {
static ngInjectableDef = defineInjectable({
factory: () => DEFAULT_IMPL,
});
static ngFactoryFn: (t) => new (t || Service)();
}
```

There are a couple scenarios that are problematic and need special
handling:
1. A user has a custom implementation of lazy-loaded modules, sets some
provider overrides, then compiles the module so it can be loaded. In a
follow-up test, the user sets different overrides for the module and
then compiles. This is problematic because we need to be sure the module
registered in the first test is not used, so we need to clear it out of
the modules list in `ng_module_factory_registration`.
2. A user has a similar lazy-loaded module factory implementation but
relies on the module being registered automatically. This can happen,
for example, as a side effect of importing the ngfactory file.

This patch changes the Ivy `DebugElement` code to always read style and
class values directly from the native element instead of reading them
through the styling contexts. The reason for this change is because Ivy
does not make use of a debug renderer and will therefore not have access
to any classes/styles applied directly through the renderer (unless it
reads the values directly from the element).

Prior to this commit, the `ngProjectAs` attribute was only included with a special flag and in a parsed format. As a result, projected node was missing `ngProjectAs` attribute as well as other attributes added after `ngProjectAs` one. This is problematic since app code might rely on the presence of `ngProjectAs` attribute (for example in CSS). This commit fixes the problem by including `ngProjectAs` into attributes array as a regular attribute and also makes sure that the parsed version of the `ngProjectAs` attribute with a special marker is added after regular attributes (thus we set them correctly at runtime). This change also aligns View Engine and Ivy behavior.
