tu: Make TPL1_DBG_ECO_CNTL1.TP_UBWC_FLAG_HINT configurable

Danylo Piliaiev requested to merge Danil/mesa:freedreno/feature/configure-TPL1_DBG_ECO_CNTL1 into main

What does this MR do and why?

On a740 TPL1_DBG_ECO_CNTL1.TP_UBWC_FLAG_HINT must be the same between all drivers in the system, somehow having different values affects BLIT_OP_SCALE. We cannot automatically match blob's value, so the best thing we could do is a toggle.

Example:

 FD_DEV_FEATURES=enable_tp_ubwc_flag_hint=0

Issue: !29358 (comment 2453178)

CC: @airidosas252 @FireBurn

I guess one of the way to automatically solve the issue is for project that uses turnip to interrogate the blob for its version and based on that enable or disable enable_tp_ubwc_flag_hint.
