[Intel-wired-lan] [PATCH 06/38] docs: kdoc_parser: use NestedMatch to handle __attribute__ on functions

[Mauro Carvalho Chehab]

Some annotations macros may have nested parenthesis, causing normal
regex parsing to fail. The __attribute__ regex is currently very
complex to try to avoid that, but it doesn't catch all cases.

Ensure that the parenthesis will be properly handled by using
the NestedMatch() logic.
