refactor(esp_system): factor the memprot panic report out of panic_arch.c

Browse Source 
Move print_memprot_err_details() and its state out of the RISC-V panic_arch.c
into port/panic_memprot.c behind panic_memprot_fill_info(), so the report can
be shared with the Xtensa PMS targets. No functional change.
