Revert "Adding PRESUBMIT check to avoid mixing C, C++ and Objc-C/Obj-C++."
This reverts commit 0c15c5332fea2bbf5fe29dd806f9f4e606eeb9b8.
Reason for revert: This causes problems in this moment. I have to fix a target in rtc_base before landing this presubmit check.
Original change's description:
> Adding PRESUBMIT check to avoid mixing C, C++ and Objc-C/Obj-C++.
>
> The error message will be something like:
>
> GN targets cannot mix .c (or .cc) and .m (or .mm) source files.
> Please create a separate target for each collection of sources.
> Mixed sources:
> {
> BUILD_GN_PATH: [
> [
> TARGET_NAME,
> [
> SOURCES
> ]
> ],
> ...
> ],
> ...
> }
