Feature - Recompile loaded programs before epoch boundary

[Lichtso]

Problem

Continuation of #31945, to not only prune old programs which were verified and compiled against the feature set of the previous epoch, but also start recompiling them for the upcoming one before it hits.

Summary of Changes

• Adds type ProgramRuntimeEnvironment.
• Adds LoadedPrograms::upcoming_program_runtime_environment_v1.
• Adds parameter recompile to Bank::load_program().
• Removes the manually managed list FEATURES_AFFECTING_RBPF.

Closing this as it does not work. There can be multiple independent forks crossing the epoch boundary, so we can only prune once the next rooting after the epoch boundary hits. In between the epoch boundary and the first root we potentially need to replay both feature sets depending on the slot, thus each Bank needs to know its program runtime environment.
