dev/core#1569: Increase Data Size for form_values column on civicrm_report_instance table

[tunbola]

Overview

Currently form_values column of the civicrm_report_instance table is of data type TEXT. This is sufficient for saving most report instances. However we have a couple of custom reports based on the Core Civi report functionality with some dynamic filters that may vary based on some conditions in the system. As such some of the reports have a lot of custom form filters fields and when these reports are saved in the database, the serialized data in the form_values column of the civicrm_report_instance table gets truncated and this renders the saved report unusable.

Before

The data type for the form_values column on the civicrm_report_instance is TEXT

After

The data type for the form_values column on the civicrm_report_instance is now LONGTEXT

I think we might need to regenerate the sql too but I'll do that after merge since I think there are some other queued changes that need it
