[CMake][runtimes] Use target specific name for all runtimes targets

[phosek]

Summary

We need to use target specific name for all runtimes targets. Target
specific name means the name of target in the LLVM build is different
from the name in runtimes build (in LLVM build, it's suffixed by the
target itself). Previously we have only used target specific names for
check targets collected through SUB_CHECK_TARGETS, but that's not
sufficient, we need to use target specific names for all targets we're
exposing in LLVM build.

Fixes PR34335.

LGTM.

As a note: at some point in the future I'd like us to get rid of the practice of using ":" to create lists of lists, instead using list of list names, which is a bit cleaner.

[phosek]

SGTM, I'll make that as a separate change.
