Setup: Sanity check for invalid table prefixes.

Browse Source 
There are some table prefixes (for example, `7e1_`), which MySQL will try and parse as values when they're note quoted in backticks. Because not everything remembers to quote their table names, it's best if we just discourage their use during setup.

Fixes #36422.
