This PR allows user-defined aliases take precedence over built-in ones, with a warning that tells there exists a built-in alias.
This PR does not allow user aliases override built-in subcommands.

$ cat .cargo/config
[alias]
b = "fetch"
build = "fetch"

$ ./target/debug/cargo b
warning: user-defined alias `b` overrides a built-in alias for `build`

$ ./target/debug/cargo build
warning: user-defined alias `build` is ignored, because it is shadowed by a built-in command
   Compiling proc-macro2 v0.4.19
   Compiling unicode-xid v0.1.0
   Compiling cc v1.0.25
(snip)

In the current version of Cargo, user aliases cannot override built-in aliases.
This behavior is keeping us from safely adding new built-in aliases without interfering existing user config.
Merging this PR will allow that.

Fixes #6221
Relating to #6218

Thanks for the PR! I think we only want to be able to shadow built-in aliases, not commands. That could cause problems for scripts using cargo. Sorry if I wasn't clear about that.

@ehuss Ah, I got it. I have changed this PR to re-disallow user aliased to override built-in commands.
