ppcmmu: Allow map dma for last byte of region.
...
cur_dma_rgn->end is the last byte of a region. It is not the byte after the region. Therefore, subtract 1 from size before doing compare.
Also add more detail to the abort messages.

ppcmmu: Check sizeof(T) explicitly.
...
I don't know if the compiler is smart enough to figure out that ((guest_va & 0xFFF) + sizeof(T)) > 0x1000) is always false when sizeof(T) == 1 so we'll add a check for sizeof(T) > 1.

Inline ppc_set_cur_instruction
...
It's used in the main emulator loop (ppc_exec_inner), and the function
call overhead adds up.
By inlining it, time to boot to the Finder using a 7.1.2 install CD
and a 6100 ROM goes from ~6700ms to ~6400ms (with clang 14 on a
M2 Max)

Clean up #includes
...
Result of running IWYU (https://include-what-you-use.org/ ) and
applying most of the suggestions about unncessary includes and
forward declarations.
Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

ppcmmu: Reduce unmapped physical memory logging.
...
Don't log consecutive accesses to unmapped physical memory addresses. This saves a couple hundred thousand lines in the log in some cases.
This is only a partial fix. Any access that isn't logged should be queued and output if a log message is output that is not this log message or after a time period.
