• Add Qualcomm Hexagon HMX (32x64c2) and HVX (1x64c2, 4x64c2) f16-gemm microkernels and HVX x16-packw (x64c2 GOI/GIO) weight packing microkernels with XNN_ENABLE_HMX build and runtime hardware detection.

• Move the backend-independent YNNPACK tests into the shared test suites.

• Wrapping object files in a static archive impacts debug info which negatively impacts profile guided opts.

• Optimize lengthening conversions (bf16 -> f32, bf8 -> f16, u8 -> s16, f16 -> f32) using ZIP1/ZIP2 with zero on AArch64 NEON and interleave/zero-extend on x86 and Hexagon HVX.
