Remove old style asm source lists for GN and Bazel

Update-Note: I believe all GN and Bazel consumers have been migrated to
the new style of asm source list, so this change should be a no-op. If
any remain that still need the old ones, either migrate them to
crypto_sources_asm and crypto_sources_nasm, or let us know.
