LOG: [libclc]: clspv: add a dummy implememtation for mul_hi (#134094)

clspv uses a better implementation that is not using a bigger side when
not available.
Add a dummy implementation for mul_hi to avoid to override the
implementation of clspv with the one in libclc.

Added: 
    libclc/clc/lib/clspv/integer/clc_mul_hi.cl

Modified: 
    libclc/clc/lib/clspv/SOURCES

Removed:

+Opt-out of libclc mul_hi implementation for clspv.
+clspv has an internal implementation that does not required using a bigger data size.
+That implementation is based on OpMulExtended which is SPIR-V specific, thus it cannot be written in OpenCL-C.
