We can't update the framework to rxjs7 until version 13, because it contains breaking changes, but we can allow users to opt into it since all of our code should be compatible.
These changes expand the allowed version range of rxjs and add an integration test to verify that we don't get compilation errors. Note that we also have a test that runs the AIO examples against rxjs 7 already (#42660).

These token interfaces will make it easier to reason about tokens in the
parser and in specs.
Previously, it was never clear what items could appear in the `parts`
array of a token given a particular `TokenType`. Now, each token interface
declares a labelled tuple for the parts, which helps to document the token
better.

Previously, the way templates were tokenized meant that we lost information
about the location of interpolations if the template contained encoded HTML
entities. This meant that the mapping back to the source interpolated strings
could be offset incorrectly.
Also, the source-span assigned to an i18n message did not include leading
whitespace. This confused the output source-mappings so that the first text
nodes of the message stopped at the first non-whitespace character.
This commit makes use of the previous refactorings, where more fine grain
information was provided in text tokens, to enable the parser to identify
the location of the interpolations in the original source more accurately.

The tests were checking that the source-span of parsed HTML nodes were

When it was tokenized, text content is split into parts that can include

The lexer now splits encoded entity tokens out from text and attribute value tokens.
Previously encoded entities would be decoded and the decoded value would be
included as part of the text token of the surrounding text. Now the entities
have their own tokens. There are two scenarios: text and attribute values.
Previously the contents of `<div>Hello & goodbye</div>` would be a single
TEXT token. Now it will be three tokens:
```
TEXT: "Hello "
ENCODED_ENTITY: "&", "&"
TEXT: " goodbye"
```
Previously the attribute value in `<div title="Hello & goodbye">` would be
a single text token. Now it will be three tokens:
```
ATTR_VALUE_TEXT: "Hello "
ENCODED_ENTITY: "&", "&"
ATTR_VALUE_TEXT: " goodbye"
```
- ENCODED_ENTITY tokens have two parts: "decoded" and "encoded".
- ENCODED_ENTITY tokens are always preceded and followed by either TEXT tokens
or ATTR_VALUE_TEXT tokens, depending upon the context, even if they represent
an empty string.
The HTML parser has been modified to recombine these tokens to allow this
refactoring to have limited effect in this commit. Further refactorings
to use these new tokens will follow in subsequent commits.

The compliance tests can check source-map segments against expectations
encoded into the expectation files. Previously, the encoding of the expected
segment was only delimited by whitespace, but this made it difficult to identify
segments that started or ended with whitespace.
Now these segment expectations are wrapped in double-quotes which makes
it easier to read and understand the expectation files.

Add a `makeTemplateDiagnostic` wrapper in the `TemplateTypeChecker`. This requiers less parameters to create template diagnostics, since the `TemplateTypeChecker` can get the templateId and mapping from it's scope with the `ts.ClassDeclartion`. The `TemplateTypeChecker` is often used to determine if a diagnostic should be produced, so it makes sense to have a function in it that helps create them.

The compiler keeps track of how a declaration has been referenced
using absolute module imports and from which path the absolute module
should be resolved from. There was a bug in how the .d.ts metadata
extraction would incorrectly use the .d.ts file itself as resolution
context for symbols that had been imported using a relative module
specifier. This could result in module resolution failures.
For example, when extracting NgModule metadata from
`/node_modules/lib/index.d.ts` that looks like
```
import {LibDirective} from './dir';
@NgModule({
declarations: [LibDirective],
exports: [LibDirective],
})
export class LibModule {}
```
and `/app.module.ts` that contains
```
import {LibModule} from 'lib';
@NgModule({
imports: [LibModule],
})
export class AppModule {}
```
then `AppModule` would have recorded a reference to `LibModule` using
the `'lib'` module specifier. When extracting the NgModule metadata from
the `/node_modules/lib/index.d.ts` file the relative import into `./dir`
should also be assumed to be importable from `'lib'` (according to APF
where symbols need to be exported from a single entry-point)
so the reference to `LibDirective` should have `'lib'` as absolute
module specifier, but it would incorrectly have
`/node_modules/lib/index.d.ts` as resolution context path. The latter is
incorrect as `'lib'` needs to be resolved from `/app.module.ts` and not
from within the library itself.

In an incremental rebuild, the compiler attempts to reuse as much
analysis data from a prior compilation as possible to avoid doing the
analysis work again. For source files without Angular behavior however,
no analysis data would be recorded such that the source file had to be
reanalyzed each rebuild, even if it has not changed.
This commit avoids the analysis of such source files by registering
these files as not containing any Angular behavior; allowing subsequent
rebuilds to avoid the analysis work.

The static interpreter assumed that a foreign function expression would
have to be imported from the absolute module specifier that was used for
the foreign function itself. This assumption does not hold for the
`forwardRef` foreign function resolver, as that extracts the resolved
expression from the function's argument, which is not behind the
absolute module import of the `forwardRef` function.
The prior behavior has worked for the typical usage of `forwardRef`,
when it is contained within the same source file as where the static
evaluation started. In that case, the resulting reference would
incorrectly have an absolute module guess of `@angular/core`, but the
local identifier emit strategy was capable of emitting the reference
without generating an import using the absolute module guess.
In the scenario where the static interpreter would first have to follow
a reference to a different source that contained the `forwardRef` would
the compilation fail. In that case, there is no local identifier
available such that the absolute module emitter would try to locate the
imported symbol from `@angular/core`. which fails as the symbol is not
exported from there.
This commit fixes the issue by checking whether a foreign expression
occurs in the same source file as the call expression. If it does, then
the absolute module specifier that was used to resolve the call
expression is ignored.
