etnaviv: stall after RS/BLT operation when draw_stall debug option is enabled

Browse Source 
RS and BLT operations can exhibit issues in some cases. To help in debugging
such issues stall after RS and BLT operations when ETNA_MESA_DEBUG=draw_stall
is enabled. In that case the FE will point right at the faulty RS/BLT
operation, instead of the next stall which may be many state loads later.
