It would be wasteful to preallocate all batch builders because the majority of them have only a single batch, while typically only one will will have many batches. Thankfully we can acurately guess which pictures will produce many batches by checking whether they have more than one cluster.

Vector reallocations in CompositeState::push_surface are taking about 2% of total frame building time before this patch. There was an effort at preallocating some with constant values but I suspect these constants haven't been updated along with picture cachign heuristics.

This patch a simple utility to help with pre-allocating vectors that we can't recycle and use it with the primitive headers.

While ideally we'd just move all of them at the top-level, there are
other things that depend on them that wouldn't then get the right
dependencies. One of them is install steps in dist/something, but there
are others, and that's a rather long pole of things requiring many
changes along with chances to break things.
So instead, we go with a simpler and more limited approach, where we
still recurse into directories to run their export tier (to run whatever
else than GeneratedFiles they have), but ensure the GeneratedFiles we
moved at the top-level are built before recursing by making
directory/export depend on them.

While currently the path given to the script is relative and doesn't
contain a directory, but will soon, and in that case, we don't want
the directory to be part of the const name (that wouldn't even be a
valid identifier).

Ideally, this kind of manual work wouldn't be required, but the frontend
doesn't provide enough information and while backend could correlate the
information, they currently don't.

Bug 1592038 implemented a means for reducing memory usage resulting from needlessly
duplicated allocation of depth buffers when rendering WR picture cache tiles via
the NativeLayer interface. This aims to keep a similarly level of memory savings
even when using NativeLayer + SWGL.
SWGL allows, as an extension beyond OpenGL, specifying an allocation size separate
from the incidental size of a texture, which can be used to render to a smaller
valid rect of a texture without continually reallocating it every time the size
of the valid rect changes within the actual tile size. This functionality is used
to keep around only a single depth texture for the SWGL compositor that is resized
to accommodate the maximum requested tile size, so that any surface or tile can
use it as desired.

`WSFragment` is created at least one instance, and at most 3 instances per
`WSRunScanner` instance. They can be managed with `AutoTArray` simpler and
we can avoid heap allocation with this approach.

Most of TelemetryController is only used in the parent process, but is
currently loaded in all processes, where it needlessly consumes tens of KB of
memory. This patch splits the parent- and content-specific parts, and only
loads each in the processes where they're needed.

Currently RendererOGL has mixed-in details of SWGL context creation which becomes messy
and slightly unanticipated based on the nomenclature and structure of RendererOGL. Based
on other work in bug 1646835, it becomes more natural to move this context creation into
the specific SWGL RenderCompositors so that RendererOGL can be agnostic to any SWGL
details.

RenderCompositorOGL currently has many responsibilities including supporting
OpenGL compositor for Linux, whole-window compositing for Mac NativeLayerCA,
and per-cache-tile compositing for Mac NativeLayerCA. With the addition of
support for SWGL, this becomes even further complicated.
It becomes advantageous to separate out RenderCompositorOGL specifically as
only the basic OpenGL compositing case, as that naturally yields a simple and
isolated RenderCompositor.
What is left over becomes RenderCompositorNative, a basis for implementing
NativeLayer-based RenderCompositors. To cleanly isolate state and details of
when HW compositing or SW compositing is being used, these are further split
off into RCNativeOGL and RCNativeSWGL versions that deal with specific
isolated details of OpenGL and SWGL respectively.
RCNativeOGL deals with just setting up OpenGL FBOs for NativeLayers.
RCNativeSWGL's new task is just to deal mapping NativeLayers and providing
SWGL FBOs for them without involving OpenGL.

RenderCompositors for SWGL that wish to provide accelerated compositing need to
subvert the existing Bind/Unbind hooks in the WR compositor. These compositors
need to keep track of their HW tiles without actually binding an OpenGL FBO
for WR to render picture cache tiles. SWGL needs to intervene and get a backing
buffer for tile from the RenderCompositor so that it can create a SWGL FBO for
WR to render the picture cache tile to.
To that end, this adds MapTile/UnmapTile as a replacement for Bind/Unbind for
those scenarios. This is done in a way that it affects only the WrCompositor of
webrender_bindings without actually altering WR's Compositor interface. This is
beneficial because WR does not have to understand the details of SWGL
integration and also so as not to complicate other users of WR such as Servo
who are not currently utilizing SWGL at all.
RenderCompositorOGL is initially modified to use these hooks in this patch. It
later became more convenient to restructure that in a follow-up patch.

This is a first implementation of a software-only SWGL RenderCompositor
that relies on the existing widget hooks for Basic compositing. It attempts
to lock the widget and get a DT whose underlying data it can supply directly
to SWGL to composite to. Critically, it does not rely on OpenGL or any other
form of HW accel to function. The interface between the RenderCompositor and
SWGL will be further refined in follow-up patches.
