docs: kdoc: parse context_lock_struct() as struct declarationdocs-nextdocs-mw

kernel-doc fails to parse struct declarations wrapped in
context_lock_struct(), e.g. struct debugfs_cancellation:

  include/linux/debugfs.h:245 ... error: Cannot parse struct or union!

Add a struct transform that expands context_lock_struct() to a plain
struct declaration, and apply the struct transforms to the whole
declaration before split_struct_proto(), matching what dump_var() and
dump_function() already do for their prototypes. The member-only
transform in dump_struct() is then redundant.

Add a regression test for the debugfs_cancellation declaration.

Fixes: 6e530e2e3119 ("debugfs: Make debugfs_cancellation a context lock struct")
