Return $this in setters to allow chaining

[Tofandel]

Pretty much all the setters in the AnalyticsData lib return void, it would be much nicer to return $this in all setters to be able to chain them

Example:
https://github.com/googleapis/google-api-php-client-services/blob/main/src/AnalyticsData/RunReportRequest.php

I wanted to write my requests like this

(new AnalyticsData\BatchRunReportsRequest())->setRequests([
    (new AnalyticsData\RunReportRequest())
    ->setDimensions([
        new AnalyticsData\Dimension(['name' => 'year']),
        new AnalyticsData\Dimension(['name' => 'month']),
        new AnalyticsData\Dimension(['name' => 'medium']),
    ])
    ->setDimensionFilter(...)
])

But without chaining, it becomes

$request1 = new AnalyticsData\RunReportRequest();
$request1->setDimensions([
    new AnalyticsData\Dimension(['name' => 'year']),
    new AnalyticsData\Dimension(['name' => 'month']),
    new AnalyticsData\Dimension(['name' => 'medium']),
]);
$request1->setDimensionFilter(...);
$batch = new AnalyticsData\BatchRunReportsRequest();
$batch->setRequests([$request1]);
