Remove dependency of compiler tests on fir2ir tests

Compiler tests use the old test infrastructure, but fir2ir tests use the
new one (tests-common-new). Removing this dependency means that now the
two big modules, `:compiler:compileTestKotlin` and
`:compiler:tests-common-new:compileTestKotlin` can be compiled in
parallel, which improves the total build time.
