[PATCH] [gdb/build] Rename gdb/gdb-gdb.py.in to gdb/gdb-gdb.py

[Tom de Vries <tdevries@suse.de>]

Currently, $build/gdb/gdb-gdb.py is generated from $src/gdb/gdb-gdb.py.in, but
there's no real need for it: they are identical.

Fix this by:
- renaming gdb/gdb-gdb.py.in to gdb/gdb-gdb.py
- using AC_CONFIG_LINKS to get $build/gdb/gdb-gdb.py

Because pre-commit type classification does not consider gdb/gdb-gdb.py.in a
python file:
...
$ identify-cli gdb/gdb-gdb.py.in
["file", "non-executable", "text"]
...
.pre-commit-config.yaml has a types_or override to stop pre-commit from
ignoring the file.  Unfortunately, that never worked for flake8, which needed
a types override instead [1].

Update .pre-commit-config.yaml to reflect the new situation:
- drop the files match for gdb/gdb-gdb.py.in
- drop the types_or override that's no longer necessary

Tested on x86_64-linux, by doing a clean build and testing gdb.gdb/*.exp.
