Description
Currently when a macro invocation creates more than one runnable test lens we give the lenses the functions name and still show them like here:
This works fine for a small number of lenses but can quickly become overwhelming, includeing bindgen output is a prime example for this:
Instead we should collapse these into one special lense that offers a selection on which test to run if a macro expands to X or more lenses.

Research direction
Start by reproducing the macro-expansion examples in the issue and tracing how runnable test lenses are generated and displayed. Determine the threshold for collapsing multiple lenses, then verify that a collapsed lens offers a test-selection menu and that small numbers of lenses retain their current behavior.
