Print the active section/generator selection

**Description**
I sometimes find it hard to correctly select the section and/or generator when digging through failing tests. A part of this is that Catch2 provides very little info about what I have actually selected with the given options.

I would like the whole test spec to be printed, just like it is when no path/section spec is given. I would also like the given filter/generator selection to be printed, just like the `Filters: ` printout.

I'm currently using Catch2 v3.14.0.

**Additional context**
This is the complete printout I currently get when I've made a selection that leads nowhere, which doesn't help me find out what I need to change to reach the expected assertion.
