v1.18: Revert deprecate executable feature (backport of #309)

[mergify]

Problem

We reevaluated the feature to deprecate executable. We felt that this feature is
too complex and too risky for v1.18.

Therefore, we would like to revert this feature.

Summary of Changes

• revert deprecate executable feature
• add a test to cover transfering lamports into native_loader owned account
