Make Lift instances more efficient

[TeofilC]

This patch allows the Lift instance to make use of the primitive bytes literals made available since template-haskell 2.16.

It also adds some extra tests to make sure the instance works correctly with multi codepoint characters.

Let me know if you'd like some changes

@phadej could you please review?

[TeofilC]

The CI failures seem to be due to the change in template-haskell 2.17 for the type of lift from a -> Q a to Quote m => a -> m a. I'll push a fix

[TeofilC]

I've force pushed to squash the fixup commit

[TeofilC]

Ah dear it seems like I dropped that commit by accident instead of squashing it. I'll fix it in a bit

[Bodigrim]

I'll squash all commits any way, so do not worry about that.

Thanks!
