mm: rename GENERIC_PTDUMP and PTDUMP_CORE
Platforms subscribe into generic ptdump implementation via GENERIC_PTDUMP.
But generic ptdump gets enabled via PTDUMP_CORE. These configs
combination is confusing as they sound very similar and does not
differentiate between platform's feature subscription and feature
enablement for ptdump. Rename the configs as ARCH_HAS_PTDUMP and PTDUMP
making it more clear and improve readability.
