Add a tile-aware abstraction layer for 2D matrix operations that lowers to target-specific code across all supported backends: - Scalar fallback: hwy.Tile[T] with nested loop implementations - NEON: TileFloat32x4/Float64x2 using vfmaq_laneq lane-broadcast FMA - AVX2: TileFloat32x8/Float64x4 using broadcast+FMA on archsimd vectors - AVX512: TileFloat32x16/Float64x8 using broadcast+FMA on archsimd vectors - C/:asm targets: AST translator emits NEON/SVE intrinsics with tile structs hwygen transforms tile operations (TileZero, OuterProductAdd/Sub, TileReadRow, TileStoreRow, TileLoadCol, NewTile, TileDim) using the existing IsMethod pattern for SIMD targets and direct hwy.* calls for fallback.
