Returns the profiling results.

By default, all profiling results will be returned. You may provide
`$categories` and `$excludeCategories` as parameters to retrieve the
results that you are interested in.

@param array $categories list of categories that you are interested in.
You can use an asterisk at the end of a category to do a prefix match.
For example, 'yii\db\*' will match categories starting with 'yii\db\',
such as 'yii\db\Connection'.
@param array $excludeCategories list of categories that you want to exclude
@return array the profiling results. Each element is an array consisting of these elements:
`info`, `category`, `timestamp`, `trace`, `level`, `duration`, `memory`, `memoryDiff`.
The `memory` and `memoryDiff` values are available since version 2.0.11.
