Mojo: Wrap the satisfied/unsatisfied wait flags state in a single object.

Mojo: Wrap the satisfied/unsatisfied wait flags state in a single object.

First, add a struct (MojoWaitFlagsState) to the public C API. We'll use
this to report additional (e.g., per-handle) information in
MojoWait()/MojoWaitMany().

Second, make a subclass struct (mojo::system::WaitFlagsState) that adds
a constructor and some simple methods for convenience (but adding no
overhead).

Third, convert our various separate handling of satisfied/satisfiable
state to use the new combined struct.
