Make MemoryAllocator limits configurable and extensible

The allocation limits on MemoryAllocator were internal with no public
way to raise the 1 GB single-buffer default, and ApplyOptions was not
callable from external subclasses, which blocked custom allocators.

- Expose MemoryGroupAllocationLimitBytes, SingleBufferAllocationLimitBytes,
  and AccumulativeAllocationLimitBytes with validated protected setters.
- Make ApplyOptions protected so derived allocators can accept options.
- Add MemoryAllocatorOptions.SingleBufferAllocationLimitMegabytes to raise
  the contiguous buffer cap up to 2047 MB without a custom allocator.
- Add public-api tests that implement a complete external allocator.
- Add behavior tests for the new option and its validation.

Refine alpha conversion and AOT seeding

Introduce explicit associated/unassociated pixel conversion APIs across `IPixel` and `PixelOperations`, and rework associated-alpha operations to use representation-aware bulk hooks. Update pixel implementations, converters, blenders, and generated code to consistently apply `Premultiply`/`UnPremultiply` semantics, plus SIMD-backed conversion paths for half and signed formats.

Fix codec and processing behavior where alpha handling was incorrect or lossy (notably TIFF/EXR decode/encode, convolution/resize/filter/normalization/dithering paths), and add targeted tests for these cases. Expand AOT compiler roots (including EXR and additional pixel/processor coverage), add a new public API test project for pixel-operations extensibility, and add broad alpha-representation and quantization regression coverage.
