* Consolidate Backend * change Backend.TRITON_V2 to Backend.TRITON * According to quantize_config.format, determine when the Backend is packing the model. * Auto choose the fastest one Backend based on quant model compatibility * fix issue: Automatically select Backend, returns incorrect qlinear. * cleanup * cleanup

Resolves #59
The following args will be merged into single backed: Backend = Backend.AUTO
use_triton: bool,
disable_exllama: bool = False,
disable_exllamav2: bool = False,
use_marlin: bool = False,
use_bitblas: bool = True,
Reason: It is not only super confusing for users to use correctly (matrix condition of passive binary toggles), even project developers ran into multiple bugs due to these passive switches. We can't keep adding more binary toggles every time we add a backend/kernel/runtime. Becoming unmaintainable and unusable by both end-users and project devs.
Prelim design:
class Backend(ENUM):
AUTO # choose the fastest one based on quant model compatibility
CUDA_OLD
CUDA
TRITON_V2
EXLLAMA
EXLLAMA_V2
MARLIN
BITBLAS
