Add free-threading optimization for ``_PyFloat_FromDouble_ConsumeInputs``

[nascheme]

Feature or enhancement

Proposal:

The free-threaded build is missing an optimized version of this function. It should generally give a small speedup on code that does binary operations on float objects.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
