Compiling plugins was originally intended to be an idempotent operation. This however starts to change as we introduce build customisations, which have the unfortunate side-effect of changing the state of the plugin directory, leading to conflicts between concurrent compilation jobs. Therefore to mitigate this problem, this commit changes how compilation jobs are processed, by introducing a global compilation queue, and processing plugins' compilation one-by-one from this queue. This however makes such requests asynchronous, so test suites that require plugins to be compiled will now have to wait on their completion before they can start their tests. To this effect, we introduce one more convenience function that processes those errors, and automatically fails the test should one compilation job fail for any reason.
