  [clang][Parser] Improve error recovery for missing semicolons in class members. (#190744)

This is something I discovered when doing the investigation for
https://github.com/llvm/llvm-project/pull/188123#issuecomment-4162665482.

This patch improves recovery when a semicolon is missing after a class
member declarations.

When the parser expects a semicolon but encounters a token that is at
the start of a line and is a valid declaration specifier, it injects a
`;` instead of skipping tokens, this allows us to preserve the
declaration after the missing ";" instead of discarding it.
