Picking up build2 and updating the Changelog

Changelog update and versions bump

The fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1443823 makes
our workaround for https://bugzilla.mozilla.org/show_bug.cgi?id=1392604
obsolete, and we can remove it as it landed on esr60.

This commit adds support for building and bundling fxc2 which is
required for Windows cross-compilation on Linux.

After building Firefox we now get a 'Tor Browser.app' instead of a
'TorBrowser.app'. This patch makes sure the additional whitespace in the
app name is correctly handled by the build script and the one that deals
with packaging the final bundle.

We need to ship a fix for the Firefox packaging step as well as
|./mach package| wants to build the final .dmg in that step, too, which
breaks: there is no .dmg creation tool available. Setting
`INNER_MAKE_PACKAGE` to `true` does not seem to work anymore. That part
of this patch is currently only a workaround to get the nightly builds
going. We should come up with a better solution that allows us to skip
that part of the Firefox packaging step on all supported platforms.

This commit fixes #26153 by bumping the selfrando version to 0.4.2

At the same time we add a var/selfrando variable to make it easier to
enable/disable selfrando.

Due to bug https://bugzilla.mozilla.org/show_bug.cgi?id=1392604 we disable
STL wrappers for now. For some reason only 64bit Windows builds are affected.
Thus we restrict the disabling only to them leaving all other targets
unaffected.

This reverts commit e0e6bfd7.

This reverts commit 409a6951.
