T.copy() does not support partial data transfer.

[fengz72]

Background

During the implementation of grouped matmul, it is necessary to transfer partial data from L0C to GM.

Root Cause

The current copy interface derives the data transfer size directly from the src shape and ignores the extent.

Proposal

Update the copy interface to support slice syntax for the src argument to enable partial data transfer, or add a default parameter to specify the copy size.
