When debugging `LView`s it is easy to get lost since all of them have
the same name. This change does three things:
1. It makes `TView` have an explicit type:
- `Host`: for the top level `TView` for bootstrap
- `Component`: for the `TView` which represents components template
- `Embedded`: for the `TView` which represents an embedded template
2. It changes the name of `LView` to `LHostView`, `LComponentView`, and
`LEmbeddedView` depending on the `TView` type.
3. For `LComponentView` and `LEmbeddedView` we also append the name of
of the `context` constructor. The result is that we have `LView`s which
are name as: `LComponentView_MyComponent` and `LEmbeddedView_NgIfContext`.
The above changes will make it easier to understand the structure of the
application when debugging.
NOTE: All of these are behind `ngDevMode` and will get removed in
production application.

The 4b81bb5c97 patch seemingly broke the
`profile_all.js` file due to the file renaming. This patch restores the
functionality of said script.

this makes running and profiling tests much easier. Example usage:
```
yarn bazel run --define=compile=aot //packages/core/test/render3/perf:noop_change_detection
```

PS: I considered moving the ng_rollup bundle into the macro but I didn't want to make
too many changes in this PR. If we find running benchmarks in this way useful, we
should refactor the build file more, and move the ng_rollup_bundle targets into the
macro.

The styling algorithm requires that the `RNode` has a `className`
property in order to execute the fast-path. This changes adds the
emulation of this property.
PR Close#33392
This patch ensures that the `[style]` and `[class]` based bindings
are directly applied to an element's style and className attributes.
This patch optimizes the algorithm so that it...
- Doesn't construct an update an instance of `StylingMapArray` for
`[style]` and `[class]` bindings
- Doesn't apply `[style]` and `[class]` based entries using
`classList` and `style` (direct attributes are used instead)
- Doesn't split or iterate over all string-based tokens in a
string value obtained from a `[class]` binding.
This patch speeds up the following cases:
- `<div [class]>` and `<div class="..." [class]>`
- `<div [style]>` and `<div style="..." [style]>`
The overall speec increase is by over 5x.

`LFrame` stores information specifice to the current `LView` As the code
enters and leaves `LView`s we use `enterView()` and `leaveView()`
respectively to build a a stack of `LFrame`s. This allows us to easily
restore the previous `LView` instruction state.

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.

This patch is a final major refactor in styling Angular.
This PR includes three main fixes:
All temporary state taht is persisted between template style/class application
and style/class application in host bindings is now removed.
Removes the styling() and stylingApply() instructions.
Introduces a "direct apply" mode that is used apply prop-based
style/class in the event that there are no map-based bindings as
well as property collisions.

Replaces the `select` instruction with a new one called `advance`. Instead of the jumping to a specific index, the new instruction goes forward X amount of elements. The advantage of doing this is that it should generate code the compresses better.
