98e4524d - [PyTorch Edge] Add OwnedOrBorrowedVector for QNNPack BCSR Indices/Values (#80476)

[PyTorch Edge] Add OwnedOrBorrowedVector for QNNPack BCSR Indices/Values (#80476) OwnedOrBorrowedVector allows us to create a BCSR which uses preexisting data pointers for its indices and values, so we can avoid copying data when loading. It also supports creating a BCSR which owns indices and values data in vectors as before.
