Adding a custom visual queue for hit condition breakpoints

[cmoscofian]

Problem Statement

Currently the hit_condition breakpoints, when available, have the same visualization as a regular breakpoint.
I think would be beneficial to add the ability to set it's own visual queue (sign and hl-group), similar to what has been done for log_point.
I might be wrong here, and if that is the case I apologize, but sounds simple enough to implement and has a fair bit of value.

Possible Solutions

I think it would be useful in the context of loop debugs where mixed breakpoints are created, meaning some parts you only care on hit_conditions and others you might want to inspect every-time. It would be good being able to visualize that the breakpoints are correctly setup on a glance, not having to run and finding out the wrong one has been setup.
