feat: remove Enable URL context and Enable Grounding with Google search checkboxes (RooCodeInc#11253)

Remove the "Enable URL context" and "Enable Grounding with Google search"
checkboxes from Gemini and Vertex provider settings, along with:

- enableUrlContext and enableGrounding fields from provider settings schemas
- URL context and Google Search tool injection in completePrompt methods
- Associated translation keys from all 18 locale files
- Related test cases updated to reflect the removal
- simplifySettings prop removed from Gemini and Vertex components
  (it was only used for the removed checkboxes in those components)
