Ed Page d840d5650e fix(derive)!: Rename Clap to Parser.
Before #2005, `Clap` was a special trait that derived all clap traits it
detected were relevant (including an enum getting both `ArgEnum`,
`Clap`, and `Subcommand`).  Now, we have elevated `Clap`, `Args`,
`Subcommand`, and `ArgEnum` to be user facing but the name `Clap` isn't
very descriptive.

This also helps further clarify the relationships so a crate providing
an item to be `#[clap(flatten)]` or `#[clap(subcommand)]` is more likely
to choose the needed trait to derive.

Also, my proposed fix fo #2785 includes making `App` attributes almost
exclusively for `Clap`.  Clarifying the names/roles will help
communicate this.

For prior discussion, see #2583
