[ENH] add hydrogen_mass and ewald_tolerance to to_openmm_simulation

[IAlibay]

Description

This is not really a need (to me), mostly something I came across whilst debugging some packmol stuff.

The to_openmm_simulation method doesn't allow you to apply HMR, or set the ewald tolerance, depending how the intended user experience, it may be worth adding these.

See:

openff-interchange/openff/interchange/components/interchange.py

Lines 596 to 602 in 57dd53a

	def to_openmm_simulation(
	self,
	integrator: "openmm.Integrator",
	combine_nonbonded_forces: bool = True,
	add_constrained_forces: bool = False,
	additional_forces: Iterable["openmm.Force"] = tuple(),
	**kwargs,

Yep, this would be a good change. Quite the hefty function signature afterwards
