Refactor {Matrix,Vector}_double_dense through ..._numpy_dense, add ..._numpy_integer_dense

[mkoeppe]

... in order to define matrix spaces backed by numpy arrays of various types
https://numpy.org/doc/stable/reference/arrays.scalars.html#signed-integer-types

For ZZ, this could for example provide a separate element implementation that is never used for arithmetic, but is good enough for creating matrices in methods such as vertex_adjacency_matrix (#32666)

setting to needs_review for the patchbot.

Still needs work to hook it into the constructor etc.

Stalled in needs_review or needs_info; likely won't make it into Sage 9.5.
