Adam Siemieniuk 67ac275fee [mlir][x86] Rename x86vector to x86 (#183311)
Renames 'x86vector' dialect to 'x86'.

This is the first PR in series of cleanups around dialects targeting x86
platforms.
The new naming scheme is shorter, cleaner, and opens possibility of
integrating other x86-specific operations not strictly fitting pure
vector representation. For example, the generalization will allow for
future merger of AMX dialect into the x86 dialect to create one-stop x86
operations collection and boost discoverability.
