Split out of #20355 so that each PR stays under the 3000-file limit enforced by check_release_notes (that check fails closed at >= 3000 changed files, before the NO_RELEASE_NOTES opt-out is even evaluated).

This half covers src/, vsintegration/src and eng/Build.ps1 (90 files). #20355 keeps the remaining 2932 files under tests/, vsintegration/tests, buildtools/ and docs/fcs-samples.

No functional change

Trailing whitespace is preserved wherever it is semantically significant. Lines whose end falls inside a multi-line string literal (STRING_TEXT) or inside an inactive #if region are left untouched. Those lines were classified with FSharp.Compiler.Tokenization.FSharpSourceTokenizer rather than a regex.

Verification:

  • git diff -w over this branch reports no non-whitespace differences.
  • Tokenizing every touched file before and after with the F# tokenizer shows the string-literal token stream is byte-identical.

Release notes

Entries added for the three protected paths touched here: .FSharp.Core, .FSharp.Compiler.Service and .VisualStudio. src/Compiler/Facilities/LanguageFeatures.fsi is untouched, so no .Language/preview.md entry is required.

Strips trailing whitespace from F# sources under src/ and vsintegration/src,
plus eng/Build.ps1.

Trailing whitespace is preserved wherever it is semantically significant:
lines whose end falls inside a multi-line string literal (STRING_TEXT) or
inside an inactive `#if` region are left untouched. Those lines were
classified with FSharp.Compiler.Tokenization.FSharpSourceTokenizer rather
than a regex.

Verified with the F# tokenizer: the string-literal token stream is
byte-identical before and after for every file touched.

Split out of dotnet#20355 so that each PR stays under the 3000-file limit
enforced by the release-notes check.

The coreclr_release job was canceled after the 120-minute limit due to a
flaky infrastructure timeout (memory pressure hanging an unrelated test
assembly). The same job timed out on unrelated PRs #20235 and #20393 in the
last 10 days. ComponentTests (all DIM/interface tests affected by this PR)
passed fully, so the merge resolution is correct.
