testsuite: Split rs6000 mma related PR test cases to dmf and nodmf

Hi Michael,

The same changes as done for 1/2 patch is done for this as well. Kindly
review and approve for trunk and gcc-16.

Thanks,
Avinash

Changes from v1:
* Use dmf, nodmf instead of p10 and future in updated test file names.
* Use powerpc_future_compile_ok for dmf tests.
* Use -mno-dense-math for nodmf tests.

All the remaining test cases which use mma functionality have been
split into power10 and future.
