rtc-screen: Incorporate color into rd cost for IDTX

IDTX mode in nonrd_pickmode is only based on Y channel,
some logic exist to bypass this mode test when color
sensitivity is set, but in some cases, even with color
detected, its still worth entering the mode test.

If color_sensitivity is set for the coding block,
and we enter the IDTX search, add terms from UV channel
into rdcost, using model_rd to avoid slowdown.

bdrate gains on speed 10 rtc screen:
avg/ovr/ssim, IC speedup
-0.493/-1.099/-1.248, 0.286

This reduces color artifacts in sc_web_browsing.
