At the same time, we make it actually do something on spidermonkey
builds. We also add an environment variable alternative, that we use
in mozconfig.stdcxx, allowing for mozconfig.no-compile to override it
and avoid configure failures on e.g. artifact builds.

We want most builds to be actually using sccache, so we include
mozconfig.cache from mozconfig.common. However, since the --with-ccache
configure option doesn't exist on non-compile jobs (e.g. artifact
builds), we move to using the CCACHE environment variable instead, which
allows us to unset it in mozconfig.no-compile.
And since mozconfig.no-compile is always included where no_sccache is
set, we can remove that variable.

LLVM_CONFIG, per the contents of toolkit/moz.configure, is tied to
--enable-stylo, but it currently is set on all types of builds. It
currently happens to work, but it's actually not meant to, and sure
enough, the fix for bug 1374727 exacerbates that.
So we create a new mozconfig.stylo file that enables stylo and sets
LLVM_CONFIG, such that only build types that do enable stylo have
LLVM_CONFIG set.
