runtime(odin): support underscore-separated numeric literals
Add support for underscore-separated numeric literals in Odin syntax
highlighting. This allows proper highlighting of numbers like 1_000_000,
0xFF_AA_BB, and 0b1010_1111 as specified in the Odin language.
> Numerical literals are written similar to most other programming
> languages. A useful feature in Odin is that underscores are allowed
> for better readability: 1_000_000_000 (one billion).
