Update ./tools/presubmit defaults and add --all mode

The new default should be quick, aarch64 tests barely take longer
than clippy/fmt and gives good enough coverage for most things.

The --all mode will add all other builds run by kokoro, including
armhf and a --no-default-features build.

BUG=b:203152778
TEST=./tools/presubmit (--quick, --all)
