[AArch64] Alter arm_neon_sve_bridge.h to be target-based, not preprocessor based.

Similar to D131064, this alters the arm_neon_sve_bridge.h header to use
target-based intrinsics that give an error if used in a function that
does not have the sve features, but are not preprocessed out. This
header is simpler than the arm_sve.h and other headers, not including
any tablegen'd content. The main change is altering the builtin
definitions from using BUILTIN to TARGET_BUILTIN.
