Move builtins-test-intrinsics out of the workspace

This crate doesn't need to be a default member since it requires the
opposite settings from everything else. Exclude it from the workspace
and run it only when explicitly requested.

This also makes `cargo t --no-default-features` work without additional
qualifiers. `--no-default-features` still needs to be passed to ensure
`#![compiler_builtins]` does not get set.

compiler-builtins needs doctests disabled in order for everything to
work correctly, since this causes an error running rustdoc that is
unrelated to features (our `compiler_builtins` is getting into the crate
graph before that from the sysroot, but `#![compiler_builtins]` is not
set).

We can also remove `test = false` and `doctest = false` in
`builtins-test` since these no longer cause issues. This is unlikely to
be used but it is better to not quietly skip if anything ever gets added
by accident.
