Adjust Graphisoft style due to feedback

Structs and unions usually don't inherit from anything in our codebase,
so these should always have their starting brace on the same line as the
struct/union keyword.

The desired line length was increased to 150 as well, due to complaints
in code reviews about 120 resulting in less readable code.

Add a release workflow using GitHub Actions

This workflow builds clang-format for Window x86, x86_64 and arm64, and
Linux x86_64, and MacOS x86_64 and arm64, then creates a GitHub release
for them.

clang-tblgen and llvm-tblgen also must be compiled for the host system
if cross-compiling before building clang-format.
