core/video_core: Use in-place construction where possible

More PICA200 Emulation Fixes

Not really sure where the difference is, but some applications seem to use this 1:1 the same way...

Pica/TextureEnvironment: Add support for the MAD-like texture combiners and clean up texture environment logic.

The change in depth range seems to reflect better to what applications are expecting, and makes for cleaner code overall (hence is more likely to reflect hardware behavior).

ConfigMem: Clean up the Config memory to be more like the shared page

vfpinstr: Fix trivial signed/unsigned mismatch warnings

dyncom: Support conditional BKPT instructions

VideoCore: Fix a typo in Vec4 MakeVec(T, Vec3<T>), where the second argument was Vec2<T> instead

the helper macro for padding to common_funcs.h

Services: Fixed "Tried to connect to named port err:f".

err:f is a named port, not a service

vfpdouble: Use %p for printing pointer addresses.

dyncom: Actually set the destination register for USAD8/USADA8.
