  [BOLT] Add an option for constant island cloning (#165778)

Avoid cloning constant island helps to reduce app size, especially for
BOLT optimization in which cloning would happen when a function is split
into multiple fragments. Add an option to make the cloning optional, and
we will introduce a new pass to handle the reference too far error that
may result from disabling constant island cloning (#165787).
