Missing documentation for some Clang Static Analyzer checks

[PiotrZSL]

In file clang/include/clang/StaticAnalyzer/Checkers/Checkers.td following checks are listed, but no such documentation exists in clang/docs/analyzer/checkers.rst:

• cplusplus.Move
• cplusplus.PlacementNew (invalid name in documentation, see: https://reviews.llvm.org/D157702)
• cplusplus.PureVirtualCall
• optin.osx.OSObjectCStyleCast (marked as NotDocumented)
• osx.MIG (marked as NotDocumented)
• osx.OSObjectRetainCount (marked as NotDocumented)
• security.insecureAPI.decodeValueOfObjCType
• valist.CopyToSelf
• valist.Uninitialized
• valist.Unterminated

Looks like property Documentation cannot be trusted, as there are checks marked as HasDocumentation without documentation, and those marked as NotDocumented with documentation (osx.ObjCProperty for example).

clang-tools-extra/docs/clang-tidy/checks/gen-static-analyzer-docs.py should be executed after adding documentation to update aliases on Clang-tidy side.
