Teresa Johnson 54a3c2a81e [ThinLTO] Add option to disable readonly/writeonly attribute propagation ...

Summary:
Add an option to allow the attribute propagation on the index to be
disabled, to allow a workaround for issues (such as that fixed by
D70977).

Also move the setting of the WithAttributePropagation flag on the index
into propagateAttributes(), and remove some old stale code that predated
this flag and cleared the maybe read/write only bits when we need to
disable the propagation (previously only when importing disabled, now
also when the new option disables it).
