LOG: [docs] Rename selected clang docs to Markdown (#206181)

Tracking issue: https://github.com/llvm/llvm-project/issues/201242
Migration guide docs:
https://llvm.org/docs/SphinxQuickstartTemplate.html#markdown-migration-guidelines
RFC:
https://discourse.llvm.org/t/rfc-make-myst-markdown-the-llvm-docs-format-rip-rest/90840

Rename 20 selected clang docs from reStructuredText to MyST Markdown
filenames.

This PR is intentionally limited to the rename phase and required
reference updates. The mechanical conversion and follow-up MyST cleanup
are in the stacked PR.

Added: 
    clang/docs/AddressSanitizer.md
    clang/docs/ClangStaticAnalyzer.md
    clang/docs/CrossCompilation.md
    clang/docs/DataFlowSanitizer.md
    clang/docs/FunctionEffectAnalysis.md
    clang/docs/LanguageExtensions.md
    clang/docs/LeakSanitizer.md
