pixman's meson detects openmp support and if it finds it in runtime then
enables it, this happens for gcc via gcc-runtime, however for clang, it
does not. In some cases e.g. mips it enables it during configure only to
find that clang can not find the libomp during linking. Therefore, add
the dependency on openmp when using clang compiler. This ensures consistent
behaviour across architectures.

Disable internal assembler on mips since it can not handle the inline assembly

Turn openmp into a packageconfig

openmp is not yet ported to all architectures e.g. RISCV32 does not have it
