Modularization of sagelib: Break out a separate package sagemath-ntl

[mkoeppe]

This distribution package would provide sage.libs.ntl and all functionality that Sage draws from NTL, mostly:

• rings.padics
• rings.polynomial
• rings.finite_rings
• rings.number_field
• matrix.cyclo_dense, .integer_dense.
• a few more random places

There are a few places from which we can eliminate the dependency on NTL as a preparation:

• sage.rings.finite_rings.element_givaro: Remove dependency on NTL #29910: sage.rings.finite_rings.element_givaro: Remove dependency on NTL
• sage.rings.integer, integer_ring: Remove dependencies on sage.libs.ntl #29911: sage.rings.integer, integer_ring: Remove dependencies on sage.libs.ntl
• sage.rings.polynomial.evaluation: Split into ..._flint and ..._ntl #29999: sage.rings.polynomial.evaluation: Split into ..._flint and ..._ntl
• Eliminate use of FLINT's NTL interface #32908 Eliminate use of FLINT's NTL interface

This is part of Meta-ticket #29705: Modularize sagelib into separate distributions (pip-installable packages). The modules are recombined with the rest of sagelib via the native namespace package functionality.
