SwitchControl text to left, right or top of control now toggles checked state

Partial resolution for #8243 since many usages do not use the built-in text
but render their own text separately. A subsequent commit will address converting these
usages.

This also converts text from span to label for accessbility and more appropriate renderer defaults (the cursor).
