[ci] Build `standalone_crt` during the build

[driazati]

Currently this happens during CI setup (cached via make):

tvm/tests/scripts/task_ci_setup.sh

Lines 34 to 36 in 16bb1a6

	python3 tests/scripts/task_build.py \
	--sccache-bucket tvm-sccache-prod \
	--cmake-target standalone_crt

We should move that into the build steps for each platform and add the artifacts to the inter-step archives as necessary
