Moves all manual render3 view_container_ref tests that use property
bindings to acceptance tests with TestBed.
Two issues surfaced and refer to a difference between Ivy and View
engine:
* Multi-slot projection is not working with Ivy: FW-1331
* ViewContainerRef throws if index is invalid while View Engine clamped index: FW-1330

Previously we defensively wrapped expressions in case they ran afoul of
precedence rules. For example, it would be easy to create the TS AST structure
Call(Ternary(a, b, c)), but might result in printed code of:
```
a ? b : c()
```
Whereas the actual structure we meant to generate is:
```
(a ? b : c)()
```
However the TypeScript renderer appears to be clever enough to provide
parenthesis as necessary.
This commit removes these defensive paraenthesis in the cases of binary
and ternary operations.

Previously, interpolations were generated into TCBs as a comma-separated
list of expressions, letting TypeScript infer the type of the expression
as the type of the last expression in the chain. This is undesirable, as
interpolations always result in a string type at runtime. Therefore,
type-checking of bindings such as `<img src="{{ link }}"/>` where `link`
is an object would incorrectly report a type-error.
This commit adjusts the emitted TCB code for interpolations, where a
chain of string concatenations is emitted, starting with the empty string.
This ensures that the inferred type of the interpolation is of type string.

This is the first refactor PR designed to change how styling bindings
(i.e. `[style]` and `[class]`) behave in Ivy. Instead of having a heavy
element-by-element context be generated for each element, this new
refactor aims to use a single context for each `tNode` element that is
examined and iterated over when styling values are to be applied to the
element.
This patch brings this new functionality to prop-based bindings such as
`[style.prop]` and `[class.name]`.

Previously, in order to assert that the promise was not resolved, an
error was thrown when the promise was resolved successfully. At the
same, `.catch()` was used to silence the (expected) promise rejection.
However, the chained `.catch()` handler would also catch (and swallow)
the error thrown on resolving the promise, making the test pass, even if
the promise was not rejected.
This commit fixes it by ensuring that the error thrown on resolving the
promise is not caught by the rejection handler.

Previously, [this test][1] would occasionally fail (e.g. on CI) with
"Template cache was not found in $templateCache". This was due to a
combination of:
1. [That test][2] (which removes the cache) being run right before the
failing test.
2. The async `TestBed.compileComponents()` operation run in the
`beforeEach()` block (which sets the cache) not having completed
before the `it()` block.
This commit fixes the issue by ensuring the cache is always set, before
instantiating `CachedResourceLoader`.
This commit also moves some operations that are only needed in one test
from the `beforeEach()` block to that test's `it()` block.

Moves most of the tests from `render3/integration_spec` into `acceptance`. Note that there are still a handful of tests left in render3, because we don't have a way of moving all of them to go through `TestBed` since they either have r3-specific assertions or we don't have access to the same APIs as the raw instructions.

Ports render3 onDestroy tests over to be acceptance tests. Removes old render3 tests if possible.
Note the onlyInIvy test for one area where Ivy has a different behavior than ViewEngine

We were on 69 for both of these platforms which is fairly old. This update also requires a temporary patch to the @bazel/karma npm package to disable chrome sandboxing on OSX as it is broken under Bazel as of chromium 73. Windows is still on Chromium 66 but updating this will require upstream changes to rules_webtesting as the archive name & executable name has changed as of 72 for Windows and hard-coded paths in rules_webtesting break things.

Previously we were relying upon the `.get()` method to return `undefined`
but it is clearer and safer to always check with `.has()` first.
PR Close#25445
Previously the same `Renderer` was used to render typings (.d.ts)
files. But the new `UmdRenderer` is not able to render typings files
correctly.
This commit splits out the typings rendering from the src rendering.
To achieve this the previous renderers have been refactored from
sub-classes of the abstract `Renderer` class to classes that implement
the `RenderingFormatter` interface, which are then passed to the
`Renderer` and `DtsRenderer` to modify its rendering behaviour.
Along the way a few utility interfaces and classes have been moved
around and renamed for clarity.

In some cases the `forwardRef` helper has been imported via a namespace,
e.g. `core.forwardRef(...)`.
This commit adds support for unwrapping such namespaced imports when
ngtsc is statically evaluating code.

Previously these fake files were full TypeScript source
files (`.ts`) but this is not necessary as we only need the
typings not the implementation.

Previously we were using an anonymous type `{specifier: string; qualifier: string;}`
throughout the code base. This commit gives this type a name and ensures it
is only defined in one place.

Previously, ngtsc would fail to evaluate expressions that access properties
from e.g. the `window` object. This resulted in hard to debug error messages
as no indication on where the problem originated was present in the output.
This commit cleans up the handling of unknown property accesses, such that
evaluating such expressions no longer fail but instead result in a `DynamicValue`.
