Performs a matmul, writing the output into a mutable PagedKVCacheCollection object.

Args:

hidden_state (LayoutTensor): Tensor with shape (sum(seq_lens), num_heads * head_size).
input_row_offsets (LayoutTensor): Tensor with shape (batch_size + 1,) denoting the start of each sequence along the seq_len dimension.
weight (LayoutTensor): Tensor with shape (num_heads * head_size, num_kv_heads * head_size).
input_scale (LayoutTensor): Scale to be multiplied to the input Tensor.
weight_scale (LayoutTensor): Scale to be multiplied to the weight Tensor.
kv_collection (PagedKVCacheCollection): The historical KVCache for keys and values. The KVCache for this layer is retrieved via layer_idx.
layer_idx (UInt32): The index of the layer being executed. Used to retrieve the KVCache for the given layer from kv_collection.
ctx (DeviceContextPtr): The call context pointer, passed by the graph compiler.
