[core] Add authentication components for @toolpad/core

[bharatkashyap]

Summary

• A <SignInPage />component that renders a sign in page similar to Studio apps with the authentication feature turned on

• Work with multiple authentication providers (Google, GitHub, KeyCloak etc.)

• Work with multiple authentication frameworks (not tightly coupled with next-auth)

• Automatically detect branding elements specified in the theme.ts file and implement them

• Allow customisation of the default look through slots

• Different components for different variants, for example: <SignInPageTwoColumn /> to allow rendering a branding asset in one column

Examples

• https://mui.com/toolpad/studio/concepts/authentication/ as the starting behaviour
