It was only possible to separate all geometry from an intersection or none.
Made this into an enum with a 3rd option to 'Cut', (now default)
which keeps each side of the intersection separate
without splitting faces in half.
- use 'Intersect' prefix for boolean and regular intersection.
hints that they use the same basic logic with different modes.
- 'split by edges' while correct - isn't very descriptive.
Works much the same as intersect operator,
expose as a new operator since for users its quite different.

Internally, this adds boolean args to BM_mesh_intersect function.
Was the case of several Mesh operators actually (and probably others, but cannot check
everything). Added `RNA_def_property_float_distance` helper, avoids having to
set PROP_DISTANCE subtype explicitly each time...
Modeling tool to cut intersections into geometry (like boolean, without calculating inside/outside).
Faces are split along intersections, leaving new edges selected.
