Add M3 text fields, selects and selection controls

Outlined and filled text fields (input, password, auto-growing textarea,
native select with the customizable select menu, file), checkbox with an
indeterminate state, radio buttons, the M3 switch and form, ported from
ReStride and extended. The first half of Phase 6.
