Curves: Hair to Curves rename in Cycles/EEVEE UI

Change uses of "Hair" in Render Settings UI in the property editor
and the "Hair Info" node to use the "Curves" name to reflect the
design described in T95355, where hair is just a use case of a more
general curves data type.

While these settings still affect the particle hair system,
the idea is that if we have to choose one naming scheme to align
with, we should choose the option that aligns with future plans
and current development efforts, especially since the particle
system is considered a legacy feature.

A few notes:
- "Principled Hair BSDF" is not affected since it's meant for hair.
- Python API property identifiers are not affected.
