Brandy Carney e5c8c10029 fix(components): include mode classes on components for use in shadow (#17838)
- removes mode-less component classes from the internal CSS, use element instead
- adds mode specific classes `md` or `ios` for styling inside of shadow components
- adds e2e test that verifies mode classes exist on all ionic components, plus checks for specific classes that the components need for internal styling
