tynasello a205695de4 [Clang] Add template argument support for {con,de}structor attributes. (#151400)
Fixes: https://github.com/llvm/llvm-project/issues/67154

{Con, De}structor attributes in Clang only work with integer priorities
(inconsistent with GCC). This commit adds support to these attributes
for template arguments.

Built off of contributions from [abrachet](https://github.com/abrachet)
in [#67376](https://github.com/llvm/llvm-project/pull/67376).
