build(binding): add universal macOS ARM64 dylib and static FreeType compilation

- Static FreeType linking flow for all OS
- Flow to build universal binaries for macOS (x86_64, aarch64)
- Simplified CI workflow by removing FreeType branches from the build matrix

Added 2 new scripts:
1. `buildSrc/scripts/vendor_freetype.sh`
2. `buildSrc/scripts/build.sh`

The first script prepares FreeType for usage in the build process.
The result of this script is used in the `GenerateLibs` task.
Other ways of building with FreeType are removed.
If it's impossible to build with FreeType, it is recommended to set `freetype=false`.

The second script aggregates commands to build native binaries.
It includes specific steps, such as creating a universal library for macOS and copying the result to the specific folder `/tmp/imgui/dst`.

Script 1 can be used for local builds. Script 2 is primarily intended for use in CI.
