[nvptx, testsuite] Remove mptx settings in gcc.target/nvptx tests

Some test-cases in gcc/testsuite/gcc.target/nvptx contain mptx
settings, which are paired with misa settings, in order to have the mptx
version support the misa version.

Since commit decde11183bd ("[nvptx] Choose -mptx default based on -misa"),
this is no longer necessary.

Remove the mptx settings.

Tested on nvptx.
