Bug 1654103: Standardize on Black for Python code in `mozilla-central`. r=remote-protocol-reviewers,marionette-reviewers,webdriver-reviewers,perftest-reviewers,devtools-backward-compat-reviewers,jgilbert,preferences-reviewers,sylvestre,maja_zf,webcompat-reviewers,denschub,ntim,whimboo,sparky

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.

To produce this patch I did all of the following:

1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.

2. Run ./mach lint --linter black --fix

3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.

4. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

As Jan pointed out in the bug, the condition for this assertion is too strong.
I assumed that only generators and async functions have resume points, but they
are also used for try-finally and table-switch.

Let's try again rather than lose the assertion entirely. The new assertion is
placed at the point where the two pieces of information (generator-ness and
fixed slot count) come together.

All stack slots are initialized to `undefined` whenever a new stack frame is
pushed. Usually this means a function's bytecode doesn't need to do anything
special to initialize local `var`s.

However, parameter default value expressions are evaluated before entering the
function's `var` scope, so any lexical bindings can use a stack slot that will
later be reused for a local `var`. This slot needs to be re-initialized to
`undefined` when entering the `var` scope.

This patch conservatively resets all previously used fixed slots, even those
that correspond to `function`s rather than `var`s.

Bug 1614465 - Replacing ASRouter calls to MessageChannel with JSWindowActors to eliminate ASRouterFeed r=k88hudson

Patch by Bernard Igiri <bigiri@mozilla.com>

Replacing async events with async method calls that use JSWindowActors to communicate with the parent process.
This will simplify these calls, bring the relevant code into local scope, and eliminate the need for MessageChannel.
Eliminating the MessageChannel dependency allows us to move the ASRouter initialization out of ASRouterFeed and into
JSWindowActors.

The toolbar will always appear on the newtab page. Profiles that already had the toolbar showing will have a migration to keep their experience unchanged.

On some Adreno devices, we are unable to blit directly to texture
arrays. To work around this, we first blit to a renderbuffer, then
copy the data from there to the destination texture.

As renderbuffers cannot be BGRA8, we currently panic when attempting
to create a renderbuffer for blitting to a BGRA8 texture. This
situation should be uncommon, as the devices which require this
renderbuffer usually don't support EXT_buffer_storage, meaning we use
RGBA8 textures.

However, we have seen instances of this panic on some esoteric
hardware configurations (x86 + Adreno GPU). To fix this, use RGBA8 for
the renderbuffer format when the texture is BGRA8.

Differential Revision: https://phabricator.services.mozilla.com/D93671

When a page doesn't have a non-empty media session metadata, we would use its title as a default metadata, which would display as an artist name on the virtual control interface.

Therefore, when a page changes its title, we should also notify media controller (if it's been created) in order to update the default metadata as well.
