* Remove IsCompilerDiagnostic, IsCompilerDiagnosticAnalyzer from DiagnosticAnalyzerInfoCache

* Separate DiagnosticAnalyzer descriptor cache from host analyzers

* Split and rename file

Move options related types that are linked into CodeStyle layer to a different namespace to avoid type name conflicts

Extracts out the changes to core Workspace changes from https://github.com/dotnet/roslyn/pull/41363.

* Move "is telemetry allowed" flag to DiagnosticAnalyzerInfoCache

* Clean up DiagnosticService

* Fixes

* Remove analyzer exception telemetry reporting.

* Remove reporting analyzer exceptions from SupportedDiagnostics.

The diagnostics will be reported when the compiler runs the analyzer on the compilation.

* Remove unused parameter

* Clean up analyzer telemetry reporting.

* Test fixes

* Feedback

This reverts commit 6ac8006e.

Fixes #19284

* Misc feedback

* Use ValueTask instead of custom task caching

* Remove project type from Bing URI

* Add Language to DiagnosticData

* Trim arguments that are too long

Also fix violations from newly added rules.

This seems to cause a noticable UI delay while the NFW gets reported. We already report the AD0001 diagnostic with exception callstack and the analysis context on which exception occurred, so user has enough information to file an actionable bug.

Add new analyzer API (DiagnosticSuppressor) to allow programmatic suppression of analyzer and/or compiler non-error diagnostics

Fixes #20242 and #30172

Detailed design proposal [here](https://gist.github.com/mavasani/fcac17a9581b5c54cef8a689eeec954a).

Added public APIs with documentation comments:

For batch compilation, suppressors always run after all the analyzer diagnostics have been computed.
For IDE partial/incremental analysis scenario, we may run the suppressors with partial diagnostics.
Suppressed diagnostics from diagnostic suppressors are equivalent to source suppressed diagnostics: they show up in the error list with "Suppression State" column as "Suppressed" and are also output to errorlog as suppressed diagnostics.

* refactor and clean up diagnostic engine code so that it can be re-used stand alone.

code refactored is related to properly set up CompilationWithAnalyzer and compute and return diagnostics

* made default diagnostic analyzer service to share code with VS diagnostic analyzer service on computing diagnostics.

unlike VS diagnostic analyzer, the default one doesn't persist data or calculate diagnostics per a analyzer to improve per analyzer freshes nor compute and maintain per project analyzers and etc.

also, this add ability to calculate semantic diagnostics for script file.

* enable semantic diagnostics for script file for misc workspace.

now, C#/VB script files in misc workspace will get semantic errors as well as syntax errors.

any language such as F# if document is added to misc workspace with SourceCodeKind.Script, they will automatically get semantic errors as well.

this PR doesn't address changes propagations for #load which was never supported for existing C#/VB script support.

* addressed PR feedbacks

this will cache compilation end analyzer info in diagnostic service so that
it can be cheap except the very first time that most likely done by solution crawler.

added tests

Fixes #25771
