Bug 1705376: Synchronize workspace-hack features and usage r=firefox-build-system-reviewers,glandium

Not all in-tree Rust libraries were using workspace-hack.
Additionally, some needed winapi features were missing from
workspace-hack's configuration.

Now, winapi is re-compiled less frequently on a full build.

We're vendoring it already so no reason not to. Only a couple dependencies left
after these to get rid of 0.6.

Bug 1601233 made cranelift bump its syn dependency to 1.0, breaking the
workspace hack. Some of the features were also stale from presumably
other updates.

The discrepancy of features used for syn between jsrust and gkrust
triggered syn and its reverse dependencies up to cranelift to be
built once for jsrust and once for gkrust, while they are time consuming
to build.

Bug 1499196 - Introduce a mozilla-central-workspace-hack crate to unify features seen by rust deps. r=ted,firefox-build-system-reviewers

This is the equivalent of the rustc-workspace-hack used by the rust build to
ensure cargo and RLS see the same set of features for dependencies so that
these dependencies may be reused by invocations of cargo for these two
projects. The trivial crate added specifies the union of the set of
features activated for a particular crate for each time it appears in the
dependency tree so that cargo will understand these dependencies to be
re-usable across cargo implementations. This eliminates re-building jsrust
and some of its dependencies twice, and reduces the number of crates compiled
in the tree by about 90 in testing on linux.
