In page_dump/dump_region, use guest_addr_max to check the
size of the guest address space and size the output
appropriately. This will change output with small values
of -R reserved_va, but shouldn't affect anything else.

This macro is used by only one target, and even then under
unusual conditions -- AArch64 with mmap's PROT_MTE flag.
Since page size for aarch64-linux-user is variable, the
per-page data size is also variable.
Since page_reset_target_data via target_munmap does not
have ready access to CPUState, simply pass in the size
from the first allocation and remember that.

"exec/exec-all.h" declares prototypes such:
void *probe_access(CPUArchState *env, vaddr addr, int size,
^^^^^
MMUAccessType access_type, int mmu_idx,
uintptr_t retaddr);
MemoryRegionSection *iotlb_to_section(CPUState *cpu,
hwaddr index,

MemTxAttrs attrs);
^^^^^^^^^^
vaddr is defined in "exec/vaddr.h", hwaddr in "exec/hwaddr.h"
and MemTxAttrs in "exec/memattrs.h". All these headers are
indirectly pulled in via "exec/translation-block.h". Since
we will remove "exec/translation-block.h" in the next commit,
include the missing ones, otherwise we'd get errors such:
