Revert "[GC] Ensure JSFunctions with flushed bytecode are flushed during GC."

This reverts commit f5729f1cdafa24e03fa9d6912dcca80c3d4ef3d8.

Reason for revert: GC Stress failures, e.g. https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot/23549

Original change's description:
> [GC] Ensure JSFunctions with flushed bytecode are flushed during GC.
> 
> When bytecode is flushed from a SFI, the JSFunctions still retain their
> FeedbackVector's and point to the interpreter entry trampoline. They are
> reset if re-executed, however if not they could hold onto the feedback
> vector indefinetly. This CL adds a pass the GC to detect JSFunctions that
> need to be reset, and performs the reset at the end of GC.
