i386: Correct ISA set for Panther Lake and Diamond Rapids

In ISE, Panther Lake does not enable PREFETCHI and Diamond Rapids
does not enable USER_MSR. Correct them accordingly.

I will backport the patch to GCC15/14. For GCC14, only PTL will be
backported.

gcc/ChangeLog:

* config/i386/i386.h
(PTA_PANTHERLAKE): Remove PREFETCHI.
(PTA_DIAMONDRAPIDS): Remove USER_MSR.
* doc/invoke.texi: Correct documentation.
