media: Use conftest to find if enum v4l2_async_match_type present

Browse Source 
Use conftest to determine if the 'enum v4l2_async_match_type'
has the "TYPE" in its name.

In Linux 6.5, with change commit 7a2259fc5182b ("media: v4l: async:
Rename V4L2_ASYNC_MATCH_ macros, add TYPE_"), the enum names has "TYPE" also.
