This change adds a new parameter `typeParametersInScope` to `DartEditBuilder.writeType`, and related methods to deprecate the previous `methodBeingCopied` parameter, which limited our ability to pass in some type parameters that are in scope.
Also fixes a TODO about testing if the `Record` feature is enabled or not.
And as a bonus, we now always write down type parameters by looking for the closest public type or falling back to `Object?` or `dynamic`.

Because ChangeBuilder can be used to modify multiple files, the EOL should come from an individual files edit builder and not from the overall ChangeBuilder.
This change renames `eol` on ChangeBuilder to `defaultEol` (since it's still useful to supply a custom default, for example when moving a class from an existing file to a new file, we want to default to the same EOL as the source file), and adds an EOL to file edit builders which is computed from the file content (and falls back to the default from ChangeBuilder if there are none).
My intention here is to not introduce any breaking changes (yet) so the ChangeBuilder constructor interface still has the "eol" named parameter (marked as deprecated) as well as the new `defaultEol` parameter.
I added a new `StringExtension` for `endOfLine` to both analyzer_plugin and analysis_server_plugin as we need this in both places (but I expect one of those projects will ultimately be dropped). This slightly differs from `CorrectionUtils.endOfLine` because it can return `null` which is a signal to fall back to the ChangeBuilder default instead of forcing its own default. (CorrectionUtils.endOfLine now uses that extension, although because of the null/default, it's likely that some - if not all - uses of this should migrate to the new extension and fall back to a default from a ChangeBuilder).

Before an assist call on a file with non-windows lineendings would first
search through the entire file for Windows line endings, then search for
the non-Windows line endings. As such Windows line endings was faster.
This CL changes the semantics slightly from "Windows line endings if
any Windows line endings exist" to "whatever line endings are first
used" which should be good.
It speeds up assist calls with non-Windows line endings:

Work towards #60635
In this change, we rework the AnalysisErrorListener deprecation to
better support users who have their own class that implements
AnalysisErrorListener. This change introduces a sealed supertype,
DiagnosticOrErrorListener, with the old implementation,
AnalysisErrorListener, and the new implementation, DiagnosticListener,
as its sole direct subclasses. Users who have implemented
AnalysisErrorListener should be able to instead implement
DiagnosticListener, and their class is an acceptable instance of
DiagnosticOrErrorListener, wherever that is needed.
In a breaking change we can drop AnalysisErrorListener and deprecate
DiagnosticOrErrorListener, and in the next breaking change, we can drop
DiagnosticOrErrorListener.
For reference, see the first API difference when deprecating AnalysisErrorListener and introducing DiagnosticListener: https://github.com/dart-lang/sdk/commit/903d77cc8229972a424941dcb7b7b79741e833eb#diff-dec15868961d7eadcd009f49d129bebcdb747aaa8dbfde5f5a08884e0cf11e32

I tried to keep this minimal but still sensible:
* Rename AnalysisErrorListener and all subtypes to use 'Diagnostic'.
* Rename all instantiations of such classes if they previously
contained the word 'error'.
* Rename `RecordingDiagnosticListener.errors` to `.diagnostics`.
* Rename some _testing_ instance members that had the word 'error'
to instead use 'diagnostic'.

This allows us to traverse the children without needing to create lists.
It also allows us to iterate over lists of nodes more efficiently.
Tested against the script that computes fixes for 10,000 diagnostics,
I'm seeing the following result.
Before this CL the average time was 10692.4 ms.
After this CL the average time was 1900.0 ms.
That's just over an 82% improvement.

Sometimes - on responding to `edit.getFixes` requests, the method
`getTopLevelDeclarations` is called several times with the same
parameter and caching has then sometimes sped things up.
I then also noticed that it caused `reportAnalysisAnalytics` to be
called many times (e.g. 73 times for one `edit.getFixes` request)
each time spending time collecting data which - on passing to
`analyticsManager.analysisComplete` - was just thrown away because it
only saves the first one.
Combined these changes have been observed to reduce the response time
on `edit.getFixes` by up (down?) to ~20% (e.g. from 5 seconds
to 1 second).
In response to http://b/407797012 where more data is also available.
Unfortunately I haven't been able to reproduce this is a benchmark
(yet anyway). I don't know if it needs slower slower reads, an extreme
amount of files, several contexts or something else entirely.

A few statements around the package read:
> Producers used in bulk fixes must not modify the FixKind during
> computation.
In fact, this `add_null_check` correction producer seems to be the
_only_ remaining producer that violates this statement. In order to
fix it, such that `fixKind` is set during constructor initialization,
we must do some poking around the AST.
So we convert `_computeTarget` to be static (and change it to also
compute and return any possible null-aware token, renaming it to
`_computeTargetAndNullAwareToken`). We also convert `_isNullAware` to
be static. Then the two public constructors are converted into
factory constructors that determine the fix kind, and store the
`_target` and `_nullAwareToken` in fields, so as to avoid re-computing
them during `compute()`.

The `DartFixContext.librariesWithExtensions` utility function accepts
a `memberName` parameter but never did anything with it. This change
adds filtering in that function based on the member name.
This code depends on the set of exported extensions, which is provided
in an extension (`LibraryElementExtensions.exportedExtensions`) in the
analysis_server package, which must be moved to the analyzer package.

This updates `analyzer_use_new_elements` lint to stop reporting inside
deprecated declarations. So, we can deprecated and prepare for removal.
Apply deprecation dart/analysis/results.dart
Deprecate `ElementDeclarationResult`, add `FragmentDeclarationResult` instead.
Change `getFragmentDeclaration` (not yet published) return type to `FragmentDeclarationResult` to better correspond to the method name.
Rename `getElementDeclaration` from `AnalysisSessionHelper` to
`getFragmentDeclaration`, to better reflect on what it operates.
