Subject: [PATCH] Alter hook_task TEXT fields to LONGTEXT (#20038)

Mysql TEXT has a limit of 64KB, change this to LONGTEXT in mysql only so we can have bigger hook payloads.

Postgresql has unlimited TEXT - https://www.postgresql.org/docs/current/datatype-character.html
Sqlite has unlimited TEXT - https://www.sqlitetutorial.net/sqlite-data-types/#:~:text=The%20maximum%20length%20of%20TEXT,SQLite%20supports%20various%20character%20encodings.

Same issue as #16656 but for hook_task

Fixes #10252, #19679, #3561
