treewide: Drop __cficanonical

Browse Source 
CONFIG_CFI_CLANG doesn't use a jump table anymore and therefore,
won't change function references to point elsewhere. Remove the
__cficanonical attribute and all uses of it.

Note that the Clang definition of the attribute was removed earlier,
just clean up the no-op definition and users.
