Added `--verbose` in the proper place in `compile.py` (#20825)
When running `compile.py` (after `configure.py`) with the `--verbose`
flag, the resulting cmake command is `cmake --build build <my_build_dir>
-- deply-sycl-toolchain --verbose` which results in an error like this
`/usr/bin/gmake: unrecognized option '--verbose'` when using Unix
Makefiles as generator. To support both makefiles and ninja, a better
and easier approach is to just place `--verbose` before the `--` in the
final command.
