feat: add runtime permission granting tools and --grant-all-permissions flag

New tools for managing browser permissions at runtime (no restart needed):
- browser_grant_permissions: Grant specific or ALL permissions at runtime
  - Supports `all: true` to grant all common permissions at once
- browser_clear_permissions: Revoke all granted permissions
- browser_set_geolocation: Set geolocation coordinates at runtime

New CLI flag:
- --grant-all-permissions: Start with all permissions pre-granted
- PLAYWRIGHT_MCP_GRANT_ALL_PERMISSIONS env var support

Permissions granted with `all: true` or --grant-all-permissions:
- geolocation, notifications, camera, microphone
- clipboard-read, clipboard-write
- accelerometer, gyroscope, magnetometer
- midi, background-sync, ambient-light-sensor
- accessibility-events
