MDL-52206 completion: New criteria to handle behaviour between modules

=== 4.0 ===
* New method mark_course_completions_activity_criteria() has been added to mark course completions instantly. It is
based on cron for completion_criteria_activity.php which is refactored to use it as well.
* Modified completion criteria to allow plugins to override core completion logic.
* Core now passes an additional parameter to '_get_completion_state'. This is an array representation of the completion results that have already been
tested. Currently contains - viewed, usegrade, passgrade. Any plugin that are dependent on these criteria can now check this array instead of retesting it.
* Introduced a new plugin function - '_get_completion_aggregation_state', that would indicate the aggregation type/relationship between the plugin and core
completion criteria. This callback should either return a COMPLETION_STANDARD_FLOW / COMPLETION_CUSTOM_MODULE_FLOW. The former for default existing core
behaviour while the latter enforces the override logic from the plugin. Defaults to COMPLETION_STANDARD_FLOW if not defined. This is useful when plugins
need to override the core completion criteria in cases where it may be dependent on them. In these cases, the 'source of truth' would be the response
from the plugin's 'get_completion_state' function. e.g. Quiz's completion defines a criteria of 'requires passing grade OR all attempts AND min attempts
reached.' In these cases, even if a passing grade has not been achieved, the activity should be marked as completed if the no.of attempts have been reached.
