stdlib: Update AbstractCore's 'set_inst_stop_any_thread'

This patch:
- Makes this function private.
- Updates the function's documentation.
- Changes the 'init' parameter to 'board_initialized'.

It doesn't make much sense for this function to be exposed directly to
the user as it requires knowing whether the board is initialized or not.

In addition to this I believe it makes more sense for the 'init' logic
to be flipped and renamed "board_initialized' so that this value is True
if the board has been initialized.

The documentation for this function has been updated.
