GHA: include runner CPU arch in cache keys (revert)

Turns out in practice the internal cache name contains the arch where it
matters (arm or dual-arch local builds), which is part of the cache key
string. Drop `runner.arch` to avoid two arch strings in the key.

Cache keys without an explicit arch designator mean intel.

Revert ff78af5752 #20234

Closes #20249
