EPR #411058 - [CQE OCL][Lnx][QR][CZ]MultiDevice_Context fails in 2.0 conformance wimpyfull due to CL# 1101352
- The detection of different map types is overcomplicated with possibility of multiple maps and multithreading environment. Thus keep USWC indirect map optimization based on the allocation flags.

EPR #410824 - [CQE OCL][CZ][S/G][QR] Two Bolt sample failing on CPU; Faulty CL: 1101352
- The test performs double maps with different map flags. Optimization could choose different map schemes for each call and memory coherency could be broken. Add extra conditions to detect multiple maps and use the same path as the first map.

EPR #410736 - [CQE OCL][ISV][QR][G] FFMPEG app generating corrupted video output; Faulty CL:1101352
- Add detection for AHP allocation.
FFmpeg uses AHP allocations with CL_MAP_READ flag, but actually performs CPU write into the buffer. With indirect map runtime executes useless transfer on map and doesn't write updated memory on unmap, because a wrong flag sent by the app.
