SWDEV-77682 - Wave Limiter: Add __attribute__((amd_hint_waves_per_simd(n))) to FE for setting waves/simd hint per kernel. 0 for adaptive wave limitting. 1~10 for fixed waves/simd. Add query of WavesPerSimdHint metadata to compiler lib. HSAI path shouls use aclQueryInfo RT_WAVES_PER_SIMD_HINT to get the waves/simd hint value. This should provide a flexible workaround for bug SWDEV-56552 [CQE OCL][PERF][LNX][QR][G] 19% Perf drop is observed with chunkBp kernel in Carrizo.
