Queries can also be statically accessed within getters. e.g.
```ts
ngOnInit() {
this.myQueryGetter.doSomething();
}
```
In that case we need to check if the `myQueryGetter` definition accesses
a query statically. As we need to use the type checker for every property acess
within lifecylce hooks, the schematic might become slower than before, but considering
that this is a one-time execution, it is totally fine using the type-checker extensively.

When an @NgModule is imported more than once in the testing module (for
example it appears in the imports of more than one module, or if it's
literally listed multiple times), then TestBed had a bug where the
providers for the module would be overridden many times.
This alone was problematic but would not break tests. However, the original
value of the providers field of the ngInjectorDef was saved each time, and
restored in the same order. Thus, if the provider array was [X], and
overrides were applied twice, then the override array would become
[X, X'] and then [X, X', X, X']. However, on the second override the state
[X, X'] would be stored as original. The array would then be restored to
[X] and then [X, X'].
Each test, therefore, would continue to double the size of the providers
array for the module, eventually exhausting the browser's memory.
This commit adds a Set to track when overrides have been applied to a module
and refrain from applying them more than once.

Prior to this change, recompilation of AOT-compiled components in TestBed may fail when template override is requested. That was happening due to the `styleUrls` field defined for a Component, thus switching its state to "requires resolution" (i.e. having external resources) at compile time. This change avoids this issue by storing styles and resetting `styleUrls` field before recompilation. Once compilation is done, saved styles are patched back onto Component def.

forEach is slower as compared to a regular loop but more importantly
this change removes an anonymous function and thus makes stack traces
shorter and easier to read (important for perf analysis).

This commit removes code duplication where we had 2 versions of a
`flatten` utility. Moreover this change results in queries using
a non-recursive version of `flatten` which should result in a better
performance of query refresh operations.

Prior to this change, Ivy version of TestBed was not designed to support the logic to avoid recompilations - most of the Components/Directives/Pipes were recompiled for each test, even if there were no overrides defined for a given Type. Additional checks to avoid recompilation were introduced in one of the previous commits (0244a2433e), but there were still some corner cases that required attention. In order to support the necessary logic better, Ivy TestBed was rewritten/refactored. Main results of this rewrite are:
* no recompilation for Components/Directives/Pipes without overrides
* the logic to restore state between tests (isolate tests) was improved
* transitive scopes calculation no longer performs recompilation (it works with compiled defs)
As a result of these changes we see reduction in memory consumption (3.5-4x improvement) and pefromance increase (4-4.5x improvement).

The API changes are due to enabling strict checks in TypeScript (via `strict: true`).
The payload size changes in `polyfills.js` are due to more browser APIs being patched in recent versions (e.g. `fetch`, `customElement v1`).

In View Engine, we used to generate empty QueryLists for content queries on root
components (though we did not actually support populating these lists). We need
to keep this behavior in Ivy for backwards compatibility. Otherwise, components
that are sometimes used as root will fail if they are relying on content query
results to always be defined.

In some cases ivy expects projectable nodes to be passed in a different order
to ViewEngine. Specifically, ivy expects the catch-all ("*") to be at index
0, whereas ViewEngine expects it to be at its position at which it was parsed
in the template.
This commit adds one test that breaks under ivy and others that just describe
more accurately what happens in corner cases.

ivy's bindingUpdated instruction is using the assertNotEqual check to make
sure that NO_CHANGE value (of type Object) is not passed as a value to be
dirty-checked. In practice it means that any value passed as a binding
value would be compared to the NO_CHANGE object.
It turns out that the assertNotEqual is using == and given
that binding values are of different type and we always compare it to the
NO_CHANGE object we were doing lots of type coercion. It resulted in calls
to expensive types conversions and calls to Object.toString().
A profiler reported ~15% of the self time spent in the assertNotEqual
but it turns out that removing type coercion speeds up Material Chips with
input scenario much more (~40ms down to ~20ms).
This PR introduces new assert method `assertNotSame` that uses strict equality
check. The new assertion is used in binding instructions to compare to
NO_CHANGE object reference.

Resolves FW-1192

In ReflectionCapabilities, when checking for own parameters of a type, inherit the types properly for classes that do have a constructor, but the constructor takes no declared parameters and just delegates to super(...arguments). This removes the need to declare trivial constructors in such classes to make them work properly in JIT mode. Without this, DI fails and injectables are undefined.

This fix corrects a bug where we were passing a binding _value_
in place of an expected binding index. This reulted in the binding
value being compared to an array length and buggy type coercion.
Fixing this bug speeds up test scenario by ~10-15%.

Previously, only directives and services with generic type parameters
would emit `any` as generic type when emitting Ivy metadata into .d.ts
files. Pipes can also have generic type parameters but did not emit
`any` for all type parameters, resulting in the omission of those
parameters which causes compilation errors.
This commit adds support for pipes with generic type arguments and emits
`any` as generic type in the Ivy metadata.

This patch is the first of a few patches which separates the
styling logic between template bindings (e.g. <div [style])
from host bindings (e.g. @HostBinding('style')). This patch
in particular introduces a series of host-specific styling
instructions and changes the existing set of template styling
instructions not to accept directives. The underyling code (which
communicates with the styling algorithm) still works as it did
before.
This PR also separates the styling instruction code into a separate
file and moves over all other instructions into an dedicated
instructions directory.
PR Close#29292
Prior to this change, we always recompile all Components/Directives/Pipes even if they were AOT-compiled and had no overrides. This is causing problems in case we try to recompile a Component with "templateUrl" or "styleUrls" (which were already resolved in case of AOT) and generally this unnecessary work that TestBed was doing is not required. This commit adds extra logic to check whether a Component/Directive/Pipe already have compiled NG def (like ngComponentDef) and whether there are no overrides present - in this case recompilation is skipped. Recompilation is also skipped in case a Component/Directive has only Provider overrides - in this situation providers resolver function is patched to reflect overrides. Provider overrides are very common in g3, thus this code path ensures no full recompilation.

Fixes the incorrect failure message or the TSLint rule that
is used within Google. The TSLint rule is not part of the
public schematic code.
Additionally in order to make it easier to understand what
action the developer needs to take, we rather print out the
expected "static: true/false" statement instead of saying that
a query needs to be static or dynamic. Dynamic is ambiguous, as
there is no `dynamic: true` option.

Fixes host listeners being inherited twice, if the sub class has its own `propMetadata`. This is related to #29170 which fixed something similar, however all of the test cases there had a super class with some metadata and a sub class that didn't have any. The issue manifested itself in the `MatTreeToggle` which inherits a listener from the `CdkTreeToggle` and adds an extra `Input` of its own, causing the listener to be added twice.

HACK: This is NOT the correct implementation for deprecatedOverrideProvider.
We do not plan to implement this at all since the API is deprecated and
scheduled for removal in V8. This hack is here temporarily for Ivy testing
until we transition apps inside Google to the overrideProvider API. At that
point, we will be able to remove this method entirely. In the meantime, we
can use overrideProvider here to test apps with Ivy that don't care about
eager instantiation. This fixes 97% of cases in our blueprint.
