core: add is_nexus() and refactor is_unpaged()

Add the function is_nexus() to tell if an address is an address
available to the nexus when non-secure virtualization is enabled
(CFG_NS_VIRTUALIZATION=y). The function is stubbed to return true for
non-null arguments if non-secure virtualization isn't enabled, else
false.

Make the argument for is_unpaged() const void * for consistency with the
is_nexus() function. The stubbed version of is_unpaged() when paging
isn't enabled is updated to perform a NULL check on the argument.

The terminology "mva" is specific for older ARM architecture which has
FCSE extension. To support multiple architecture, it would be good to
rename "mva" to common terminology, such as "va". This PR renames "mva"
to "va" in TLB operations for ARM64 and RISC-V. For ARM32, "mva" is
reserved because it is really defined in ARM32's documentations.

core: mm: Introduce next_level field of struct core_mmu_table_info

The address translation rule is architecture specific, e.g., ARM adopts
increasing style while the address is translated to finer-grained table,
while RISC-V adopts decreasing style. Therefore, we add a "next_level"
field into the struct core_mmu_table_info, which represents the next
finer-grained translation level. By doing this, we can decouple the
core address translation rule from architecture specific manner.
