Add MA0197 to disallow inheritdoc on types

[meziantou]

This adds a project-style rule for <inheritdoc> usage: allow it on members, but report it on type declarations.

The motivation is to enforce a members-only documentation inheritance style without changing MA0196's existing behavior.

What changed

• Added MA0197 (InheritdocShouldNotBeUsedOnTypes) and implemented a new analyzer on SymbolKind.NamedType.
• Kept MA0196 unchanged so it remains focused on non-inheriting members.
• Added tests covering class/interface usage, partial declarations, member usage, and cref cases.
• Added docs/Rules/MA0197.md and updated docs/comparison-with-other-analyzers.md.
• Regenerated analyzer docs and packaged editorconfig files.

Notes for reviewers

• This behavior is intentionally stricter than official <inheritdoc> guidance and stricter than SA1648 for inheriting types.
• MA0197 reports type-level <inheritdoc> even when cref is present, by design for this style policy.
