Gregory Szorc 7d078ee731 Bug 1412431 - Remove support for MOZ_BUILD_PROJECTS; r=nalexander 
This was mainly used to support Universal MacOS builds, which were
removed several months ago.

In theory, someone could be using this feature to build multiple
applications with one build system invocation. But given that client.mk
is no longer the preferred interface to the build system and multiple
applications can be built by running `mach build` with different
mozconfigs, I don't think support for this feature is worth keeping.

This commit removes support for MOZ_BUILD_PROJECTS and related
functionality from client.mk. Support for recognizing
MOZ_CURRENT_PROJECT in configure and mozconfig evaluation has also
been removed. This includes support for the ac_add_app_options
mozconfig function.

Good riddance.
