A few basic presets have been setup, allowing to compile collector in
release or debug mode, as well as using sanitizers and valgrind.
CMakeUserPresets.json can be used to add other dedicated presets that
people could need. Where possible, presets are now being used, sometimes
providing other definitions that could be needed. In order to prevent
presets from being broken by future changes, a schema validation
pre-commit hook has been added that should also be enforced in CI.

Lastly, some option directives have been added to
collector/CMakeLists.txt as an additional effort to have a centralized
place for these to be defined and provide default values for them.
