The old handling of Unicode escape sequences seems partially obsolete and unnecessarily complicated. For our purposes, Rust's u32 to char parsing should be exactly what we want. Due to fish treating certain code points specially, we need to check if the provided character is among the special chars, and if so we need to encode it using our PUA scheme. This was not done in the old code, but is now. Add tests for this. Fixes #12081 Rework the error message for invalid code points. The old message about invalid code points not yet being supported seems odd. I don't think we should support this, so stop implying that we might do so in the future. In the new code, indicating that a Unicode character is out of range is also not ideal, since the range is not contiguous. E.g. `\uD800` is invalid, but \U0010FFFF is valid. Refrain from referring to a "range" and instead just state that the character is invalid. Move formatting of the escape sequence into Rust's `format!` to simplify porting to Fluent. Closes #12118
