mips: Decide to map PAGE_EXEC in map_address
This commit addresses QEMU Bug #1825311:
mips_cpu_handle_mmu_fault renders all accessed pages executable
It allows finer-grained control over whether the accessed page should
be executable by moving the decision to the underlying map_address
function, which has more information for this.
As a result, pages that have the XI bit set in the TLB and are accessed
for read/write, don't suddenly end up being executable.

Fixes: 2fb58b73746e ('target-mips: add RI and XI fields to TLB entry')
