Add github workflow, Add CMake, Add dockcross

[bensuperpc]

• Add CMake (And module for LTO, CCache, ect...)
• Add github workflow (Tests ect...)
• Add dockcross (cross-platform compiler in docker)

How can we test this? Step by step instructions please.

With CMake + Ninja:

1. cmake -S . -B build -G Ninja && ninja -C

   With CMake only build:

2. cmake -S . -B build && cmake --build build

   With Dockcross (CMake and Ninja in docker):

   For linux aarch64

3. ./tools/dockcross-cmake-builder.sh linux-arm64 -DCMAKE_BUILD_TYPE=Release

   For android aarch64

4. ./tools/dockcross-cmake-builder.sh android-arm64 -DCMAKE_BUILD_TYPE=Release

   For linux x86_64 with clang

5. ./tools/dockcross-cmake-builder.sh linux-x64-clang -DCMAKE_BUILD_TYPE=Release

   For Windows ARMv7

6. ./tools/dockcross-cmake-builder.sh windows-armv7 -DCMAKE_BUILD_TYPE=Release

What happened before?

No CI and tests every push and merge

What should happen with this fix?

Improve code quality

Anything else we should know about this patch?

Honestly I never liked the stale bot. The owner of this repo doesn't have enough free time to respond to the pulls and issues in time, so they just get closed. Another thing I've seen is that you add tests for A TON of linux distros and a set for Windows ARM without macOS or Windows x64. I'm not that into github actions, but it also seems like those are only names and you simply run them all on Ubuntu. Correct me if I'm wrong, but this is extremely concerning.

Original author doesn't seem responsive and it looks like overkill for this small project.

I think we should close this for now.

I'm sorry, I didn't see the notification, I agree, it's a bit overkill, I will simplify the PR
