Implement program filter in Reports > Programs.

[tomalec]

This is a follow-up after #96

Story

At the Google Listings & Ads > Reports > Program section Merchants will be able to filter program(-s) to see the data for.

Filter options include:

• All Google programs
• Single program
• Comparison

When Selecting a single program the filter will behave like the WooCommerce Admin Analytics > Variations equivalent filter, for example:

Event tracking

• Track event when filter is used (gla_filter)

Aditional notes

The feature was not implemented right away due to issues with setting up the <FilterPicker> component:

• Search component does not accept static options Array in autocomplete woocommerce-admin#6061,
• FilterPicker does not forward all props to Search component woocommerce-admin#6062

This feature is almost done, in already merged PRs, like #537

The only thing left is that on the first-page load, when a single program is selected its label is not rendered.

Closing as mostly done, with the follow-up #651
