rP9e82cfcc214b: Use utf8_general_ci for "sort" columns in old MySQL

Summary

Fixes T7287. This trades off 4-byte character support for case insensitivity in these columns, which is a much better trade on the balance.

Also adds more warnings about old MySQL. Note that we already issue a warning when you run "storage adjust" (which I've made stronger) and already "strongly recommend" MySQL 5.5 or newer in the install documentation.

Test Plan

Ran storage adjust --disable-utf8mb4 to go to old definitions, then ran storage adjust to get back to the new ones. Everything seemed OK in both cases.
Verified that utf8mb4 data can be migrated out of these colums with --unsafe (which will truncate).
Verified that manual explains this.
Faked my way into the setup warning.
