Alex Crichton 1faf5b9f00 Add a -Zbuild-std-features flag ...

This flag is intended to pair with `-Zbuild-std` as necessary to
configure the features that libstd is built with. This is highly
unlikely to ever be stabilized in any form (unlike `-Zbuild-std` which
we'd like to stabilize at some point), but can be useful for
experimenting with the standard library. For example today it can be
used to test changes to binary size by disabling backtraces.

My intention is that we won't need a `--no-default-features` equivalent
for libstd, where after rust-lang/rust#74377 is merged we can
unconditionally specify default features are disabled but the default
set of features lists `default`. That way if users want to override the
list *and* include the default feature, they can just be sure to include
`default`.
