This avoid repeating the enums both in the compiler and in
the runtime library, and register them in a bunch of other places.
So it should be easier to add enums and enum values
Since cbindgen doesn't see through the macro, generate the enum
manually
- We need to make sure that the initialization of global is in the right order.
- In C++ and rust, we need to add accessor to the global component
- There can be `PropertyReference::Global` in binding of globals
- The interpreter globals need to hold references to the global they may depend on
Fixes#175
Move "internal" crates into the `internal` directory. This first batch
includes most of sixtyfps_runtime but leaves the rendering backends
alone for now.
pre-commit applied some cleanups to the moved files:
- Consistent newline at end of file policy
- trimming trailing whitespace
- Formatting Cargo.toml files.
