[Tarantool-patches] [PATCH 3/4][v2] cmake: introduce 'check' and 'LuaJIT-checkpatch' targets

[Sergey Bronnikov via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

From: Sergey Bronnikov <sergeyb@tarantool.org>

In Tarantool we use our own fork of checkpatch [2] with additional check
types. It's logical to use it in a LuaJIT development. We don't need
check tags in commit messages like NO_DOC, NO_CHANGELOG, NO_TEST and
others, so to be able to customize command-line options Github Action, provided
by checkpatch repository [3], was added to the repository.

See documentation for used checkpatch in [4].

Patch introduce new CMake targets: LuaJIT-checkpatch, that checks
patches on top of master branch using script checkpatch.pl [1], and
target check, that combines LuaJIT-luacheck and LuaJIT-checkpatch.
