Remove ppc_cur_instruction global variable
...
Replace it wth an explicit opcode parameter that is passed around. That
is both slightly easier to reason about (to trace where it comes from)
and slightly faster, since it can be read from a register.
On my machine takes booting to "Welcome to Macintosh" being output in
a verbose boot of Mac OS X 10.2.8 from 31.8s to 30.6s (average of 5
runs, measured using deterministic mode and looking at when execution
reaches PC 0x90004a88).

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.

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.
