flatten rustc_lexer::character_properties module
...
On the call site, `rustc_lexer::is_whitespace` reads much better than
`character_properties::is_whitespace`.

remove XID and Pattern_White_Space unicode tables from libcore
...
They are only used by rustc_lexer, and are not needed elsewhere.
So we move the relevant definitions into rustc_lexer (while the actual
unicode data comes from the unicode-xid crate) and make the rest of
the compiler use it.

Audit uses of apply_mark in built-in macros
...
Replace them with equivalents of `Span::{def_site,call_site}` from proc macro API.
The new API is much less error prone and doesn't rely on macros having default transparency.

syntax_pos: NO_EXPANSION/SyntaxContext::empty() -> SyntaxContext::root()
...
For consistency with `ExpnId::root`.
Also introduce a helper `Span::with_root_ctxt` for creating spans with `SyntaxContext::root()` context
