Rollup merge of #141004 - matthewjasper:unicode-before-expansion, r=davidtwco

Report text_direction_codepoint_in_literal when parsing

The lint is now reported in code that gets removed/modified/duplicated by macro expansion, and spans are more accurate so we don't get ICEs from trying to split a span in the middle of a character.

This removes support for lint level attributes for `text_direction_codepoint_in_literal` except at the crate level, I don't think that there's an easy way around this when the lint can be reported on code that's removed by `cfg` or that is only in the input of a macro.

Fixes #140281
