migration: Drop migration_is_idle()
Now with the current migration_is_running(), it will report exactly the
opposite of what will be reported by migration_is_idle().
Drop migration_is_idle(), instead use "!migration_is_running()" which
should be identical on functionality.
In reality, most of the idle check is inverted, so it's even easier to
write with "migrate_is_running()" check.

migration: Drop migration_is_setup_or_active()
This helper is mostly the same as migration_is_running(), except that one
has COLO reported as true, the other has CANCELLING reported as true.
Per my past years experience on the state changes, none of them should
matter.
To make it slightly safer, report both COLO || CANCELLING to be true in
migration_is_running(), then drop the other one. We kept the 1st only
because the name is simpler, and clear enough.

A small number of migration options are accessed by migration clients,

migration: export fewer options
A small number of migration options are accessed by migration clients,
but to see them clients must include all of options.h, which is mostly
for migration core code. migrate_mode() in particular will be needed by
multiple clients.
Refactor the option declarations so clients can see the necessary few via
misc.h, which already exports a portion of the client API.

When migration for cpr is initiated, stop the vm and set state
RUN_STATE_FINISH_MIGRATE before ram is saved. This eliminates the
possibility of ram and device state being out of sync, and guarantees
that a guest in the suspended state remains suspended, because qmp_cont
