Tdl 20909 Add premade reports with dimensions filters

[leslievandemark]

Description of change

Adds two premade reports, conversions_report and in_app_purchases, and hard codes their dimension filters in the client class.

Manual QA steps

• It's not worth adding a tap tester test for these premade reports with filters. Mainly because the dimension in the filter is not selected in the premade reports, so we would not be able to make any assertions on the dimension being filtered. Also, we have no data whatsoever for in_app_purchases
• Tested conversions_report manually, by running the report with isConversionEvent selected and without, and confirming the records received are the same.
• Tested conversions_report without the filter syncs more records
• Tested that in_app_purchases can complete a sync, but not records were synced.

Risks

• Our test account doesn't have any purchaser data, so I was unable to test thatin_app_purchases synced the correct rows.
