Fix DEB and RPM dependency spec + test building docs in CI (#426)

* Update cmake/rocprofiler_config_packaging.cmake

- rocprofiler_set_package_depends which ensure CPACK_DEBIAN_PACKAGE_DEPENDS, CPACK_RPM_PACKAGE_REQUIRES, and component variants are properly formatted

* Update continuous_integration.yml

- Set ROCPROFILER_DEP_ROCMCORE to ON (test multiple dependencies)
- Set ROCPROFILER_BUILD_DOCS to ON (test building/packaging docs)

* Update docs/CMakeLists.txt

- remove '--' after cmake -E env
