x86: Remove ARCH_CET_LEGACY_BITMAP [BZ #25397]
Since legacy bitmap doesn't cover jitted code generated by legacy JIT engine, it isn't very useful. This patch removes ARCH_CET_LEGACY_BITMAP and treats indirect branch tracking similar to shadow stack by removing legacy bitmap support. Tested on CET Linux/x86-64 and non-CET Linux/x86-64. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
