[WIP] Feature/magma free

[a-sevin]

This is a proposition to remove magma dependency (but still optional)

When I writing this PR, it's not compiling on ArchLinux but it does on CeontOS 8 (could be a bug of the arch gcc).
What's changing ?

• cudacomppsinv uses CUDACOMP_magma_compute_SVDpseudoInverse_cli with USE_MAGMA=ON else CUDACOMP_cusolver_compute_SVDpseudoInverse_cli
• there are 2 new CLI functions :
  • cudacomppsinv_magma for CUDACOMP_magma_compute_SVDpseudoInverse_cli
  • cudacomppsinv_cusolver for CUDACOMP_cusolver_compute_SVDpseudoInverse_cli

I also reworked cudacomp_types.h to be remove MAGMA functions calls.

Thanks Arnaud. Note that if the speed is maintained (RT MVM: critical; SVDs: non critical but convenient), we have no problems with dropping magma altogether, to get rid of some #ifdefs.

What is the status of removing the MAGMA dependency?
