remove variables on lines 21-26, 34-36 and add them directly in the functions.

Done.

can we make check_webview_licenses and findbugs a single option like
'--host-tests' ?

don't we always want to compile?

Done. Compile comes from a boolean option now.

add option --experimental instead of separate step
