Add Button role to clickable icons and text on login/onboarding screens

Several clickable elements on the login and onboarding flows (the
account provider list items, the search clear icon, the login clear
icon, and the hidden dev-mode version tap) use plain
Modifier.clickable without a semantics role. Screen readers announce
these as generic elements instead of buttons, so users relying on
TalkBack cannot tell they are interactive.

Add role = Role.Button to each clickable modifier, and reuse the
existing clear-icon content description as onClickLabel where one is
available.
