Remove using namespace std from remaining header files

It's somewhat of an anti-pattern, and can lead to conflicts with
other symbols (e.g. the Windows build failure in https://github.com/dingusdev/dingusppc/actions/runs/11762906342/job/32766290288 ,
I removed `using namespace std` from timermanager.h to fix that one).

ppc: Use a unified opcode lookup table
...
Instead of a primary opcode lookup table with 64 entries and a few
smaller tables with 4-2048 entries, use a single 64 * 2048 (128K)
entry table to dispatch opcodes.
Helps with performance, since we avoid the function call overhead for
some frequently-used instructions (e.g. branch, integer, floating point).
Saves ~2 seconds from the time to Welcome to Macintosh (same measurement
methodology as #125 )
Secondarily also makes opcode registration/decoding a bit more uniform,
and scannable, since it's now all in initialize_ppc_opcode_table.
