Rename `cfg_match!` to `cfg_select!`

At [1] it was pointed out that `cfg_match!` syntax does not actually
align well with match syntax, which is a possible source of confusion.
The comment points out that usage is instead more similar to ecosystem
`select!` macros. Rename `cfg_match!` to `cfg_select!` to match this.
