6738d7472e ppcmmu: Add a function to get phys address. 
Since the function is for the debugger during stepping or disassembly, don't do extra logging.

3a5a70b56d ppcmmu: Allow convert virtual to physical address. 
The TLBEntries allow converting virtual guest address to virtual host address but there's no easy way to get a guest physical address for debugging purposes.
Add a phys_tag field to fix that.

6582536591 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)

35c86ad6bf 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.

ac64f9e30d ppcmmu: Fix mmio read/write offset calculation. 
For TLBs referencing an mmio region, calculate an offset that will translate a guest virtual address to an offset in the mmio region.
