treewide: update rules_rust to v0.53.0
This updated our patches for rules_rust, removes a transition as it can
be replaced with the "platform" field in the rust_binary rule. This then
allows us to correctly reference it in all targets that depend on it.
Additionally the -target parameter is replaced inside the llvm-efi
toolchain with --target=.
