Allow some imports of RLF to fail

[mkoeppe]

The RealLazyField implementation is tied closely to real_mpfr.

We modify some imports for the purpose of modularization, in particular sagemath-polyhedra (#32432)

In particular for ... is RLF tests:

$ git grep 'is RLF'
src/sage/rings/complex_double.pyx:        if S is ZZ or S is QQ or S is RDF or S is RLF:
src/sage/rings/number_field/number_field_base.pyx:        if codomain is AA or codomain is RLF:
src/sage/rings/real_double.pyx:        if S is ZZ or S is QQ or S is RLF:
src/sage/schemes/plane_conics/con_number_field.py:                if not (isinstance(p, Map) and p.category_for().is_subcategory(Rings())) or p.codomain() is AA or p.codomain() is RLF:

This failure is not from this ticket:

sage -t --long --random-seed=321172385432269463934777057410284981568 src/sage/rings/integer.pyx  # 1 doctest failed

This failure is likely from random seed fuzzing, not this ticket:

sage -t --long --random-seed=321172385432269463934777057410284981568 src/sage/rings/polynomial/multi_polynomial_ring_base.pyx  # 1 doctest failed

reported in #32544.

Replying to @mkoeppe:
