Examples will be able to use the logo from their location in `../../../logo/xxx.svg`
Some other things that needs to have the logo in their directory can use symlinks.
But because of the situation of windows, we can't use symlink for things our users
need to build and this is the case for the compiler-internal (because the C++ build
use the code from the repository), so there is a copy of the 'full' logo in
internal/comoiler/widgets/common
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.
