Experiment: Some tweaks to the Grease Pencil pie menu layout

Split off selection tools and copy (+ a few others not previously included)
into secondary "Select..." and "More..." pie menus accessible from the first.
This helps balance out the menu more in order to have consistency between
edit and non-editmode (i.e. the toggle option is now always in the same place),
as well as opening up more space for new tools to become accessible.

It does however seem a lot clunkier than the previous approach...
