feat: Optimize EvmGasManager further

[0xVolosnikov]

What ❔

1. We can remove popEVMFrame function since we are using transient storage
2. Manual return in assembly block is cheaper for some reason

This pull request changes the structure of transient storage in EvmGasManager, so it will require small chang in the compiler tester.

Observed benchmark result:
