SDC *.component.yml metadata is cached aggressively, gets in the way of component development

This also ties in to Experience Builder: #3463999-9: [PP-1] Auto-generate Component config entities for all discovered SDCs that meet XB's minimum criteria → .

Hi Wim,

I would prefer we do not introduce a new mechanism (in settings.php or in config with form in some admin page...) specific to SDC, so proposal 3 looks the best to me.

Fyi, for XB component development, I use this from Wim regularly :)

drush sql:query "DELETE FROM config WHERE name LIKE 'experience_builder.component.%'"

Here is a starting point proposition for case 3.

I would like to add tests but it seems there is only Kernel tests at the moment for component, a Unit test would perhaps be better.

So is consensus to use #3? So we can update the remaining tasks so it's clear what's being proposed here.

Test failures appeared to be random.
Applied a super nitpicky return type as a new function.
Tagging for tests
