target/loongarch: Allow user enable/disable LSX/LASX features

Some users may not need LSX/LASX, this patch allows the user
enable/disable LSX/LASX features.

e.g
'-cpu max,lsx=on,lasx=on'   (default);
'-cpu max,lsx=on,lasx=off'  (enabled LSX);
'-cpu max,lsx=off,lasx=on'  (enabled LASX, LSX);
'-cpu max,lsx=off'          (disable LSX and LASX).
