[mlir][bufferization] Ownership-based deallocation: Allow manual (de)allocs (#68648)
Add a new attribute `bufferization.manual_deallocation` that can be
attached to allocation and deallocation ops. Buffers that are allocated
with this attribute are assigned an ownership of "false". Such buffers
can be deallocated manually (e.g., with `memref.dealloc`) if the
deallocation op also has the attribute set. Previously, the
ownership-based buffer deallocation pass used to reject IR with existing
deallocation ops. This is no longer the case if such ops have this new
attribute.
This change is useful for the sparse compiler, which currently
deallocates the sparse tensor buffers by itself.
