Pull request overview

This PR updates the .NET API reference ECMAXML docs by removing <altmember> cross-references that point to obsolete/deprecated APIs (CAS permissions, legacy serialization/formatters, reflection-only load APIs, deprecated networking/threading members, etc.), aligning with issue #12513’s effort to reduce legacy guidance and references.

Changes:

• Removed many <altmember> entries that reference obsolete/deprecated APIs across BCL, WPF, networking, serialization, and collections docs.
• Reduced “See also”/related cross-links to legacy framework-era APIs (for example, CAS permission types and formatter-based serialization surfaces).
• Simplified some self-referential or legacy-API reference blocks in collection and permission-related docs.
