62e1b79cb0 MDL-65067 analytics: Strengthen format_weeks detection 
The public function get_section_dates($section, $startdate = false) is
only defined in format_weeks, not in format_base.

As other formats can (and format_topcoll has) declare a different
get_section_dates public method, merely checking that it exists is not
sufficient to guarantee that it can be called with just a section object.

Check that the format either is, or is a subclass of format_weeks.

fccc728fcc MDL-64783 analytics: Performance improvements 
- Removed redundant query to analytics_predict_samples
- Analysers API now uses recordsets to iterate through the analysable
  elements. They take the last analysed time into account.
- New method for targets so there is no need to always update the last
  analysis time. Useful for lightweight targets.

f54a4092c7 MDL-61667 analytics: Remove duplicated capability checks 
\core_analytics\model::create and \core_analytics\model::enable methods
are called from install/upgrade scripts. Therefore, they should not
include any capability check. Their capability checks are actually
redundant, as the user capabilities are already checked in the
entry-point scripts.

606c3be0f6 MDL-61667 analytics: Create missing models on install/upgrade 
Similarly to how the scheduled tasks work, we now automatically check
and make sure that all the models specified in the component's
db/analytics.php file exist during the installation or upgrade of the
component.

aa8af6fcfc MDL-61667 analytics: Fix checking that a given model does not exist 
The original implementation did not work well for checking that the
given model does NOT exist. If no record was found in the
analytics_models table, the code execution continued and it reached the
moment when indicators were checked. If no indicators were provided, the
call ended up with error 'array_keys() expects parameter 1 to be array,
boolean given' (because indicators were set to false).

3b7c7918f3 MDL-61667 analytics: Deprecate the add_builtin_models() method 
The functionality of the \core_analytics\manager::add_builtin_models()
method is to be replaced with automatic update of models provided by the
core moodle component. There is no need to call this method explicitly
any more. Instead, adding new models will be done by updating the
lib/db/analytics.php file and bumping the core version.

4de4d1652b MDL-61667 analytics: Don't autoenable models with time splitting defined 
When the API had originally been designed, it was assumed that the
presence of the time splitting method implies no requirement for the
machine learning backend and that it is a sign of less performance
demanding models. So it seemed to be safe and useful to have such models
automatically enabled. That assumption did not prove to be valid. Most
of the time is spent calculating indicators that depend on log tables.

We realized it would be useful to be able to specify the default time
splitting method without the need to have such models auto-enabled.
