[Modules][Diagnostic] Mention which AST file's options differ from the current TU options. (#101413)
Claiming a mismatch is always in a precompiled header is wrong and
misleading as a mismatch can happen in any provided AST file. Emitting a
path for a file with a problem allows to disambiguate between multiple
input files.

Use generic term "AST file" because we don't always know a kind of the
provided file (for example, see `ASTReader::readASTFileControlBlock`).
