Adds a pref to perform about:blank document loads which have system
triggering principals within the existing process, rather than doing a
process switch. This can be used in performance tests which load
about:blank and do not expect process switches.

Adds a new preference javascript.options.use_fdlibm_for_sin_cos_tan (default
false) and uses fdlibm for Math.sin, Math.cos, and Math.tan conditioned on it.

MOZ_WEBRENDER=0 now does nothing -- you will either get HW-WR or SW-WR
depending on the platform configuration. The pref
gfx.webrender.force-legacy-layers is removed. This leaves no
configuration option to disable WebRender.
MOZ_WEBRENDER=1 will continue to force WR on, which will ensure in CI we
get HW-WR unless gfx.webrender.software is true.

This basically reverts the changes in 5caa81103c00 (bug 1435671). In that bug
we switched from having a templated method to using a templated function
that returned a lambda because the templated method caused a binary size
regression on windows (MSVC). Since Firefox 67 we no longer support MSVC.
Using a lambda also required capturing the arguments by value, so it was
slightly inefficient.
This patch removes NS_MutatorMethod and makes the Apply method a template.
This improves perfomance as we can just pass the arguments to the called
function, without worrying about needing to copy them.
Since MSVC is not supported anymore, and clang and gcc didn't report a
binary size regression, this is a much better solution.

Chrome has removed 3DES completely[0], but we're still seeing some uses of it
in telemetry. Our assumption is that this is either due to old devices that
can't be upgraded, and hence probably use TLS 1.0, or servers that bafflingly
choose 3DES when there are other, better, ciphersuites in common.
This patch allows 3DES to only be enabled when deprecated versions of TLS are
enabled. This should protect users against the latter case (where 3DES is
unnecessary) while allowing them to use it in the former case (where it may be
necessary).
NB: The only 3DES ciphersuite gecko makes possible to enable is
TLS_RSA_WITH_3DES_EDE_CBC_SHA. This patch also changes the preference
corresponding to this ciphersuite from "security.ssl3.rsa_des_ede3_sha" to
"security.ssl3.deprecated.rsa_des_ede3_sha".

This is a large refactoring of the DocumentChannel process switch codepath,
with the end goal of being better able to support future process switch
requirements such as dynamic isolation on android, as well as the immediate
requirement of null principal handling.
The major changes include:
1. The logic is in C++ and has less failure cases, meaning it should be harder
for us to error out unexpectedly and not process switch.
2. Process selection decisions are more explicit, and tend to rely less on
state such as the current remoteType when possible. This makes reasoning
about where a specific load will complete easier.
3. Additional checks are made after a "WebContent" behavior is selected to
ensure that if an existing document in the same BCG is found, the load will
finish in the required content process. This should make dynamic checks such
as Android's logged-in site isolation easier to implement.
4. ProcessIsolation logging is split out from DocumentChannel so that it's
easier to log just the information related to process selection when
debugging.
5. Null result principal precursors are considered when performing process
selection.
Other uses of E10SUtils for process selection have not yet been migrated to the
new design as they have slightly different requirements. This will be done in
follow-up bugs.

Now, Gecko is the only browser to support undocumented `KeyEvent.initKeyEvent`.
We should drop it by default because `typeof KeyboardEvent.initKeyEvent` is
used at least in a major web-site and which causes not working the web-site.
