RFC: https://github.com/vllm-project/vllm-ascend/issues/4629
Reason:
There are various types of masks here, and some of them do not have a
caching mechanism. As a result, the masks need to be initialized for
each layer, leading to waste of video memory.
At the same time, we hope to standardize the management and usage of
masks.
So we have gathered all the masks into the AttentionMaskBuilder class.
Todo:
1. remove spec_attn_mask; @LICO1314
2. remove pcp_prefill_mask; @LICO1314
