Rollup merge of rust-lang#77558 - thomcc:defaults-toml-extension, r=jyn514

Rename bootstrap/defaults/{config.toml.PROFILE => config.PROFILE.toml}

This allows these files to have okay syntax highlighting in editors, and helps avoid nagging from editors which want to suggest that I install a plugin for `*.library` files to view the `config.toml.library` or whatever.

It's a very minor change.
