target: disable CONFIG_PROC_PAGE_MONITOR on most targets

Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled
for virtual targets such as malta or potent ones like x86.

This saves up to 4KB of uncompressed kernel size and significantly
decreases CPU load under certain workloads.
