Abseil Team 8fa9461cc2 Fix FunctionMocker compilation slowdown in 9d21db9e0a60a1ea61ec19331c9bc0dd33e907b1
The slowdown appears to be due to an implicit conversion of distinct (yet semantically identical) lambdas to `std::function`. Lifting out the lambdas into functors that don't get re-instantiated reduces compilation times by nearly half.

Fixes #4156
