ANDROID: Add CONFIG_LLD_VERSION

CONFIG_LLD_VERSION was originally added in commit d5750cd3 ("kbuild:
Disable CONFIG_LD_ORPHAN_WARN for ld.lld 10.0.1"), which is not
applicable to 4.19. Additionally, lld-version.sh was eliminated and
combined into ld-version.sh in commit 02aff859 ("kbuild: check the
minimum linker version in Kconfig") and there was a follow up fix in
commit 1f09af06 ("kbuild: Fix ld-version.sh script if LLD was built
with LLD_VENDOR"), which is a little large to take into
android-4.19-stable for the sake of fixing an LTO issue.

Add scripts/lld-version.sh but based on the upstream version of
ld-version.sh so that we benefit from the fixes but do not have to
backport a ton of patches just to get access to CONFIG_LLD_VERSION.
