[vm] Allow native functions to reflect over the stack frame context. #265_147

[sahithiacn]

Motivation

• This gives access to ExecutionState (stack frame of calls) to native functions. This is needed e.g. to implement programmatic access to the address of the calling function.

• Also added another feature stacktrace which allows to enable stack trace capturing and only that in the VM. Currently, this is guarded by a feature testing for UTs which is to general.
