x86/unwind: Rename unwinder config options to 'CONFIG_UNWINDER_*'
commit 11af847446ed0d131cf24d16a7ef3d5ea7a49554 upstream.
Rename the unwinder config options from:
CONFIG_ORC_UNWINDER
CONFIG_FRAME_POINTER_UNWINDER
CONFIG_GUESS_UNWINDER
to:
CONFIG_UNWINDER_ORC
CONFIG_UNWINDER_FRAME_POINTER
CONFIG_UNWINDER_GUESS
... in order to give them a more logical config namespace.
