Refactor: Use instruction_trace instead of instruction_context_stack (#22988)

Browse Source 
* Moves stack_height of the instruction_trace into InstructionContext.

* Uses nesting_level instead of stack_height internally in transaction_context.rs

* Uses the instruction_trace instead of the instruction_context_stack internally.

* Adds feature gate: record_instruction_in_transaction_context_push.
