[video_core/maxwell3d] compute macro param address on demand (#4067)

GetMacroAddress only reads a couple of indices per macro, but ProcessMacro was
then building a full std::vector GPUVAddr> with one push_back per parameter word
every submission. macro_segments already holds base, count per chunk, so
GetMacroAddress can just walk it instead, drops the per-word loop, a
.clear(), and a vector member.

Also makes it so it returns on the first match in the macro dispatch instead of running every
std::get_if check.
