This commit updates `lighthouse` to version 7.0.0.
It also adds a `width` attribute to the `code-icon.svg` image on the
homepage, which was pointed out as missing in the Lighthouse report.
(Explicit `width`/`height` attributes on images help reduce the
[layout shift][1] of the page.)

As part of the `setup` CI job (which is a prerequisite for all other CI
jobs), we rebase the current code on master to make sure the PR changes
are compatible with the latest code from master, even if the PR has not
been rebased recently.
When it is not possible to automatically rebase (i.e. when there are
conflicts that need to be resolved manually), the job and subsequently
the entire workflow should fail.
This behavior has been accidentally broken in #39592, so that the job
would succeed even if the rebase operation failed.
This commit fixes it by ensuring the `exec()` helper used in
`rebase-pr.js` will throw an error if the underlying command execution
fails. Previously, the function would always return stdout output as a
string and attach a `code` property indicating the exit code of the
command.
Since the exit code isn't necessary in the `rebase-pr.js` script, this
commit simplifies the `exec()` helper by making it return the stdout
output as a plain string (without extra properties) and re-throw any
errors (unless the `ignoreError` argument is set to `true`).

Escape the content of the strings so that it can be safely inserted into a comment node.
The issue is that HTML does not specify any way to escape comment end text inside the comment.
`<!-- The way you close a comment is with "-->". -->`. Above the `"-->"` is meant to be text
not an end to the comment. This can be created programmatically through DOM APIs.
```
div.innerHTML = div.innerHTML
```
One would expect that the above code would be safe to do, but it turns out that because comment
text is not escaped, the comment may contain text which will prematurely close the comment
opening up the application for XSS attack. (In SSR we programmatically create comment nodes which
may contain such text and expect them to be safe.)
This function escapes the comment text by looking for the closing char sequence `-->` and replace
it with `-_-_>` where the `_` is a zero width space `\u200B`. The result is that if a comment
contains `-->` text it will render normally but it will not cause the HTML parser to close the
comment.

Currently when `ɵɵtemplate` and `ɵɵelement` instructions are generated by compiler, all static attributes are
duplicated for both instructions. As a part of this duplication, i18n translation blocks for static i18n attributes
are generated twice as well, causing duplicate entries in extracted translation files (when Ivy extraction mechanisms
are used). This commit fixes this issue by introducing a cache for i18n translation blocks (for static attributes
only).
Also this commit further aligns `ɵɵtemplate` and `ɵɵelement` instruction attributes, which should help implement
more effective attributes deduplication logic.

Durring analysis we find template parse errors. This commit changes
where the type checking context stores the parse errors. Previously, we
stored them on the AnalysisOutput this commit changes the errors to be
stored on the TemplateData (which is a property on the shim). That way,
the template parse errors can be grouped by template.
Previously, if a template had a parse error, we poisoned the module and
would not procede to find typecheck errors. This change does not poison
modules whose template have typecheck errors, so that ngtsc can emit
typecheck errors for templates with parse errors.
Additionally, all template diagnostics are produced in the same place.
This allows requesting just the template template diagnostics or just
other types of errors.

Refactors the i18n error tests to be unit tests in ngtsc_spec.ts. There
is two reasons for doing this.
First is that the tests in compliace_old expected an expection to be be
thrown but did not fail the test if no exception was thrown. That means
that this test could miss catching a bug. It is also a big hacky to call
compile directly and expect an exception to be thrown for diagnostics.
Also, this can easily be unit tested and an end-to-end test is not
necessary since we are not making use of the goldfiles for these tests.
It is easier to maintain and less hacky to validate that we get helpful
error messages when nesting i18n sections by calling getDiagnostics
directly.

This commit temporarily excludes classes declared in .d.ts files from checks
regarding whether providers are actually injectable.
Such classes used to be ignored (on accident) because the
`TypeScriptReflectionHost.getConstructorParameters()` method did not return
constructor parameters from d.ts files, mostly as an oversight. This was
recently fixed, but caused more providers to be exposed to this check, which
created a breakage in g3.
This commit temporarily fixes the breakage by continuing to exclude such
providers from the check, until g3 can be patched.

This comit adds support for autocompletion of attributes that create
structural directives. Such completions differ from those of normal
attributes, as the structural directive syntax creates a synthetic
<ng-template> node which has different attributes from the main element.
PR Close#40032
This commit introduces an `isStructural` flag on directive metadata, which
is `true` if the directive injects `TemplateRef` (and thus is at least
theoretically usable as a structural directive). The flag is not used for
anything currently, but will be utilized by the Language Service to offer
better autocompletion results for structural directives.
PR Close#40032
This commit adds attribute completion to the Language Service. It completes
from 3 sources:
1. inputs/outputs of directives currently present on the element
2. inputs/outputs/attributes of directives in scope for the element, that
would become present if the input/output/attribute was added
3. DOM properties and attributes
We distinguish between completion of a property binding (`[foo|]`) and a
completion in an attribute context (`foo|`). For the latter, bindings to
the attribute are offered, as well as a property binding which adds the
square bracket notation.
To determine hypothetical matches (directives which would become present if
a binding is added), directives in scope are scanned and matched against a
hypothetical version of the element which has the attribute.
PR Close#40032
This commit adds two new APIs to the `TemplateTypeChecker`:

The `annotations` package in the compiler previously contained a registry
which tracks NgModule scopes for template type-checking, including unifying
all type-checking metadata across class inheritance lines.
This commit generalizes this utility and prepares it for use in the
`TemplateTypeChecker` as well, to back APIs used by the language service.
PR Close#40032
This commit expands the autocompletion capabilities of the language service
to include element tag names. It presents both DOM elements from the Angular
DOM schema as well as any components (or directives with element selectors)
that are in scope within the template as options for completion.

This commit extends the template targeting system, which determines the node
being referenced given a template position, to return additional context if
needed about the particular aspect of the node to which the position refers.
For example, a position pointing to an element node may be pointing either
to its tag name or to somewhere in the node body. This is the difference
between `<div|>` and `<div foo | bar>`.

The `deploy-to-firebase.js` tests rely on git info retrieved from the
`angular/angular` repository (via `git ls-remote ...`).
Previously, different calls to `git ls-remote ...` could return
different values if a new commit was pushed or a new branch was created
during test execution, resulting in errors ([example CI failure][1]).
This commit makes the tests more stable by memoizing the result of
`git ls-remote ...` and returning the same result for subsequent calls
with the same arguments (even if meanwhile the remote has been updated).

Projects opened in the LS are often larger in scope than the compilation
units seen by the compiler when actually building. For example, in the LS
it's not uncommon for the project to include both application as well as
test files. This can create issues when the combination of files results
in errors that are not otherwise present - for example, if test files
have inline NgModules that re-declare components (a common Angular pattern).
Such code is valid when compiling the app only (test files are excluded, so
only one declaration is seen by the compiler) or when compiling tests only
(since tests run in JIT mode and are not seen by the AOT compiler), but when
both sets of files are mixed into a single compilation unit, the compiler
sees the double declaration as an error.
This commit attempts to mitigate the problem by forcing the compiler flag
`compileNonExportedClasses` to `false` in a LS context. When tests contain
duplicate declarations, often such declarations are inline in specs and not
exported from the top level, so this flag can be used to greatly improve the
IDE experience.

When `checkTypeOfPipes` is set to `false`, the configuration is meant to

However, we still should produce some information about the pipe for the

pipes so that it also includes information about the pipe's class
instance as it appears in the TCB.

The TCB utility functions used to find nodes in the TCB are currently
configured to ignore results when an ignore marker is found. However,
these ignore markers are only meant to affect diagnostics requests. The
Language Service may have a need to find nodes with diagnostic ignore
markers. The most common example of this would be finding references for
generic directives. The reference appears to the generic directive's
class appears on the type ctor in the TCB, which is ignored for
diagnostic purposes.
These functions should only skip results when the request is in the
context of a larger request for _diagnostics_. In all other cases, we
should get matches, even if a diagnostic ignore marker is encountered.
PR Close#40071
