A few cosmetic fixes (#858)

* [DYNAREC] Don't include pthread.h in C files.

It's already included from box64context.h.

Since there's no pthread.h on Win32, including it only once avoids
having to add ifdefs everywhere.

* [DYNAREC] Remove some duplicate definitions of the GETG helper macros.

* Declare void functions with an explicit void.

To avoid 'function declaration is not a prototype' warnings when using
-Wstrict-prototypes.

* Avoid including bridge_private.h in files that don't need it.

* Avoid defining ZYDIS_RUNTIME_ADDRESS_NONE.

It's not used, and conflicts with the original Zydis headers.
