Fixes N/A

Summary/Motivation:

There is repeatable bug in the interaction between capture_output and any of the *_v2 solvers in contrib.solver due to the way the TextIO_or_Logger domain validator was working. A minimal reproducible example of the bug:

import pyomo.environ as pyo
from pyomo.common.tee import capture_output

m = pyo.ConcreteModel()
m.x = pyo.Var([1,2],initialize=1, bounds=(0, None))
m.eq = pyo.Constraint(expr=m.x[1]*m.x[2]**1.5 == 3)
m.obj = pyo.Objective(expr=m.x[1]**2 + m.x[2]**2)

solver = pyo.SolverFactory("ipopt_v2")
with capture_output():
    solver.solve(m, tee=True)

Changes proposed in this PR:

• Slightly change the logic in TextIO_or_Logger
• Add tests to ensure correct behavior, both alone and under capture_output
