This patch is not ideal: if would be better to do the defaulting in
`toolkit/moz.configure`, but doing it there runs into problems with base
toolchain configurations, as the clang there is not new enough. So we
have this, doing everything with environment variables, which is easily
turned on or off, depending on the needs of the specific configuration.
The `mozconfig.no-compile` change is not really needed, as the wasm
sandboxing detection bits are not conditional on
`--enable-compile-environment`. Those bits should be, and I will tackle
doing that after the holidays.

This change introduces a "github-sync" component into tools,
which aims to support synchronizing both wgpu and WebRender with github.
~~It also features a "cargo test" job for standalone wgpu (bug 1596127)~~
The code is ported from "gfx/wr/scripts/wrupdater" folder. Changes are:
1. remove explicit WR parts and make them configurable by command line params
2. detect "mozilla-xxx" tags and use them in addition to the commits
As a follow up, wrupdater will be removed in favor of github-sync.
Status:
- [x] get the CI test job working
- [x] get @kats to fork "wgpu" github for "moz-gfx" bot
- [x] remove the wgpu testing CI job (into separate PR)
- [x] create new secret and reference it

The doubling of `when` is needed: the `try_run` when ensures that we
only execute the compiler on OS X, and the `@depends` when ensures that
we don't look at the `None` result (which would normally indicate
failure) on non-OS X hosts.

This is needed to support min() / max() / clamp(), as LengthPercentage will have
a potential heap allocation and the current copy-assignment operators just do
bitwise copies.

-Wempty-init-stmt is a new clang diagnostic that diagnoses empty C++17 init-statements of if, switch, and range-based for statements:
void test() {
if(; // <- warning: init-statement of 'if' is a null statement
true)
;
switch (; // <- warning: init-statement of 'switch' is a null statement
x) {
...
}
for (; // <- warning: init-statement of 'range-based for' is a null statement
int y : S())
;

We can remove our backported objcopy patches, we'll need to update
llvm-mingw for toolchain fixes, and we need to add binutils to compile
this newer version of clang because the system binutils is too old.

We've long handled chunks by defining the total number of chunks in our CI
configuration, and then passing that value down into the test harnesses at task
runtime (via the '--this-chunk' and '--total-chunks' parameters). The test
harness then runs an algorithm to determine which tests should be run in "this"
chunk.
There are several problems with this approach, but by far the biggest is that
we can't use test information in our scheduling algorithms. The information
simply isn't available yet. This patch switches things around such that we
determine which tests go in which tasks during the taskgraph generation. This
means we have perfect information around which tasks are running which tests,
and if e.g a ccov or machine learning algorithm deems a particular test
important, we can make sure to *only* schedule the tasks that contain that
test.
I'm planning to enable this a couple suites at a time so we don't accidentally
stop running tests. This specifically only enables this mode for
'mochitest-media', 'mochitest-browser-chrome' and 'mochitest-devtools-chrome'.
I chose these suites because they are the ones that are already using the
'chunk_by_runtime' algorithm.

Make the $PYTHON3 build var point to a full virtualenv bootstrapped with
the same libraries as the $PYTHON Python 2 build var. This allows us to
upgrade build tasks from $PYTHON to $PYTHON3.
This patch adds some debug logging and documentation to the Python
2 virtualenv so that it is easier to diagnose issues that may arise
from running two different Python interpreters in re-entrant
multiprocess routines.
