Convert all CRLF to LF

[Copilot]

Several text files in the repo contained CRLF line endings, inconsistent with the LF-only policy enforced via .gitattributes.

Changes

• ASCII text files — stripped \r from SUPPORT.md and .azuredevops/dependabot.yml
• UTF-16 LE JSON testdata files — removed the UTF-16 LE CRLF sequence from buildmodel/publishmanifest/testdata/msGo.output.manifest.json; this required binary-level patching since sed only handles byte-oriented encodings
• buildmodel/buildassets manifest testdata preserved as-is — buildmodel/buildassets/testdata/*/msGo.output.manifest.json files are kept in their original UTF-16 LE CRLF format because they represent real-world pipeline output that the parser must handle in production
• Binary files left unchanged — PNG images and patch/testdata/moremath.pack (git bundle) contain legitimate \r bytes and are not text files

Safeguards for buildmodel/buildassets testdata

• Added buildmodel/buildassets/testdata/.gitattributes marking */msGo.output.manifest.json as -text (binary) so git will never normalize their line endings
• Added a checkManifestIsUTF16LECRLF check inside TestBuildResultsDirectoryInfo_GoldenCreateSummary that fails with a clear message if the UTF-16 LE BOM or CRLF sequences are ever stripped from these files

@copilot it's important that msGo.output.manifest.json keep UTF-16 LE CRLF sequences. This is what this program has to parse in the wild, so it's important to test it. Revert these files to their old state and add a .gitattributes to buildmodel/buildassets that explains this.

Also, add a check to TestBuildResultsDirectoryInfo_GoldenCreateSummary that ensures the test data is in this format, so this change won't be made accidentally in the future.

Done in fc7378d:

• Reverted buildmodel/buildassets/testdata/1.23dev-publish/msGo.output.manifest.json and 1.23dev-missing-publish/msGo.output.manifest.json to their original UTF-16 LE CRLF format.
• Added buildmodel/buildassets/testdata/.gitattributes marking */msGo.output.manifest.json as -text (binary) so git won't normalize their line endings.
• Added checkManifestIsUTF16LECRLF helper in TestBuildResultsDirectoryInfo_GoldenCreateSummary that fails with a clear restore-from-source-control message if the BOM or CRLF sequences are missing.
