Add wider support for T_from_p_h for fluid properties

[GiudGiud]

Motivation

This is needed in multiple places:
according to #12108, it's needed in SAM in a branch
it's used by subchannel in the initialization phase
It's going to be used by the main Navier Stokes solver

Design

Implement T_from_p_h directly in each of the fluid properties object

• either figure out the math to invert h(p, T) usually
• or use Newton (on h(p, T))
• or use the derivation in SinglePhaseFluidProperties (can be expensive, through s_from_h_p, rho_from_p_s, e_from_v_h)

Impact

More useful fluid properties module
Faster FP computations
