  [CIR] Add ASTVarDeclInterface for AST attribute access (#179825)

Add the ASTVarDeclInterface which provides methods to access clang AST
VarDecl information from CIR attributes. This interface enables:
- mangleStaticGuardVariable: Mangle guard variable names using clang's
  MangleContext
- isLocalVarDecl: Check if a variable is function-local
- getTLSKind: Get thread-local storage kind
- isInline: Check if the variable is inline
- getTemplateSpecializationKind: Get template specialization info
- getVarDecl: Direct access to the underlying VarDecl pointer

This infrastructure is needed for proper handling of static local
variables with guard variables in LoweringPrepare.
