RCAL-900: fix numpy 2.0 issues with bitflags in resample

[mcara]

Resolves RCAL-900

Closes #1279

This PR addresses an incompatibility in the build_mask function used by the resample step with numpy 2.0. This PR deprecates this function and instead switches to the equivalent function from astropy.nddata.bitmask.

I ran a regtest through the new GitHub Actions system here:
https://github.com/spacetelescope/RegressionTests/actions/runs/10578026904
It nominally fails but the failures are the same as on main and are unrelated to this PR, so the regtest looks good to me. Code looks good to me, thanks.
