Boris Tsirkin 2849146823 Disable clang-format in Matlab files
Matlab files extension is the same as ObjC, which is .m
This makes clang-format think that those files are ObjC and then it
wrongly formats them, leading to output that doesn't compile at all.
It's a known issue and the solution is to disable it in Matlab files.

I don't want to disable ObjC in whole folders, because of 2 reasons:
1) I want ObjC to be properly formatted if new files are added in the
   future
2) C++ header files are interpreted as ObjC and it will disable their
   formatting

According to clang documentation
(https://clang.llvm.org/docs/ClangFormatStyleOptions.html#disabling-formatting-on-a-piece-of-code), we can disable formatting inline.
However, comments in Matlab are prefixed with `%` and not `//`, so I
thought of a kinda hacky solution, which is `% // clang-format off`, and
it works perfectly.

No-Iwyu: Includes didn't change and it isn't related to formatting
