Tokenize emoji as if they were valid indentifiers
...
In the lexer, consider emojis to be valid identifiers and reject
them later to avoid knock down parse errors.

Suggest `br` if the unknown string prefix `rb` is found
Currently, for the following code:
```rust
fn main() {
rb"abc";
}
```
we issue the following suggestion:
```
help: consider inserting whitespace here
|
2 | rb "abc";
| --
```
With my changes (only in edition 2021, where unknown prefixes became an error), I get:
```
help: use `br` for a raw byte string
|
2 | br"abc";
| ^^
```

Reserve prefixed identifiers and string literals (RFC 3101)
...
This commit denies any identifiers immediately followed by
one of three tokens `"`, `'` or `#`, which is stricter than
the requirements of RFC 3101 but may be necessary according
to the discussion at [Zulip].
