Add an optional mode to env_get_string()
The mode restricts the scope in which the variable is searched for.
Use this new restricted scope functionality in the `set` builtin. This
fixes `set -g` to not show local shadowing variable values, and also
allows for scoped erasing of slices.

In erase mode, if variable indices are specified, only the specified -slices of the array variable will be erased. When erasing an entire -variable (i.e. no slicing), the scope of the variable to be erased can -be specified.
