toolchain/toolchain-external: drop Synopsys ARC toolchain
This toolchain is from 2024.06 and has not been updated since then. It
was marked as broken in commit 11a8cdd2bb
in January 2025.
A warning was sent to Synopsys ARC people in December 2025, and
despite a reply that some effort would be made [1], no contributions
were actually done. Also, Alexey Brodkin is no longer at
Synopsys. Time to remove Synopsys ARC specific toolchain and toolchain
components.
