I18n: improve keymap translations

- The label for modal keymaps was extracted but did not use the proper
  context on translation.
- Same goes for modal keymap items.
- Extract the UI messages from rna_keymap_ui.py
- Translate global keymap names.
- Use the proper context in the status bar for the tool prompt operator
