LoongArch: Fix architectural naming typo for CSR_FWPS_SKIP
According to the LoongArch Reference Manual, the single-step 'Skip' bit
resides in the instruction breakpoint status register (CSR.FWPS), rather
than the configuration register (CSR.FWPC).
Furthermore, the kernel code comments also explicitly document it as
"CSR.FWPS.Skip", yet the macro was erroneously defined as CSR_FWPC_SKIP
and used as such in traps.c and hw_breakpoint.c. This mismatch creates
architectural naming confusion.
Fix this by renaming the macro from CSR_FWPC_SKIP to CSR_FWPS_SKIP to
precisely match the manual and comments. Also, update all call sites to
align with the rectified definition.
