fix: wrong data type for CL_PROGRAM_NUM_DEVICES

[MrTroble]

for clGetProgramInfo must be cl_uint (4 byte) instead of size_t (8 byte for some) [1]
for clGetContextInfo must be cl_uint (4 byte) instead of size_t (8 byte for some) [2]

Thanks for the contribution looking good from here, I'll fix the CI issues, seems we haven't updated the scripts in a while.
