Add compile_commands.json CMake script, and Lapce runners (#302)

* Add Lapce runner to run CMake

This is necessary to generate the compile_commands.json file which
clangd uses to be able to load libaries like gtkmm.

* Move compile_commands generation script into separate file

* Add more Lapce run settings

* Set execute bit on gen_compile_commands.sh

* Move Lapce run files to .lapce
