sched_ext: Drop "ops" from scx_ops_enable_state and friends

The tag "ops" is used for two different purposes. First, to indicate that
the entity is directly related to the operations such as flags carried in
sched_ext_ops. Second, to indicate that the entity applies to something
global such as enable or bypass states. The second usage is historical and
causes confusion rather than clarifying anything. For example,
scx_ops_enable_state enums are named SCX_OPS_* and thus conflict with
scx_ops_flags. Let's drop the second usages.

Drop "ops" from scx_ops_enable_state and friends. Update scx_show_state.py
accordingly.
