Intel oneAPI: add support for icx and ifx on Microsoft Windows along with win32fe_icx and win32fe_ifx wrappers

Currently ifx lacks support for DLLEXPORT - hence can be used only with --with-shared-l

Keep any (near) null space attached to submatrices in PCFIELDSPLIT even if the nonzero structure of the original matrix changes.

Keep any (near) null space attached to submatrices in PCFIELDSPLIT even if the nonzero structure of the original matrix changes.

Also applied to PCBJACOBI and PCASM

Reported-by: "Jeremy Theler (External)" <jeremy.theler-ext@ansys.com>

The long-term way to handle this is to have MatGetSubMatr*() reuse the same submatrix objects even if the nonzero structure changes. This would just require a bit of recoding in multiple places.
