Don't spin up the ART runtime in art_standalone_dex2oat_cts_tests.
It was mistakenly based on CommonRuntimeTest, which starts a runtime
through unstable APIs. The test should only run dex2oat with minimal
arguments to make --force-palette-compilation-hooks work.
Some refactoring in Dex2oatEnvironmentTest and CommonArtTest to
separate out the scratch directory creation code.
Test: atest Dex2oatCtsTest
Check with temporary logging in
system/libartpalette/palette_android_partner.cc that
PaletteNotify(Start|End)Dex2oatCompilation still gets called.
