Auto merge of #38249 - arielb1:special-substs, r=nikomatsakis

erase lifetimes when translating specialized substs

Projections can generate lifetime variables with equality constraints,
that will not be resolved by `resolve_type_vars_if_possible`, so substs
need to be lifetime-erased after that.

Fixes #36848.
Empowering everyone to build reliable and efficient software.
