Allow enabling/disabling breakpoints (#27280)

This PR adds the ability to enable/disable breakpoints. It also fixes a
bug where toggling a log breakpoint from the breakpoint context menu
would add a standard breakpoint on top of the log breakpoint instead of
deleting it.

todo: 
- [x] Add `BreakpointState` field Breakpoint that manages if a
breakpoint is active or not
- [x] Don't send disabled breakpoints to DAP servers - in progress
- [x] Half the opacity of disabled breakpoints - in progress
- [x] Add `BreakpointState` to database
- [x] Editor test for enabling/disabling breakpoints
- [ ] Integration Test to make sure we don't send disabled breakpoints
to DAP servers
- [x] Database test to make sure we properly serialize/deserialize
BreakpointState

Release Notes:

- N/A
