remove gdb feature guard for sandbox config

- the user experience is not great as the fields and methods
related to gdb port are not accessible unless the gdb feature
is turned on.
- if one runs the build command in the cli and provides the --features gdb
the IDE will not know that the feature is enabled and will show
errors as it doesn't know about the fields/methods
