layout_2020: Use the containing block more when calculating scrolling overflow
When calculating scrolling overflow calculation we cannot currently use
the actual containing block in all cases. This change increases the
amount that we do use the containing block.

Add a simple implementation of CanvasRenderingContext2d.fillText
<!-- Please describe your changes on the following line: -->
I added a simple implementation of CanvasRenderingContext2d.fillText.
Some code are merged from @mikrut, and I fixed a bug about text scaling.
Also, the bug of text rotation should be fixed after `raqote` merged my other PR.

Add support for tracking containing blocks when doing inline layout.
This requires setting up a PositioningContext for inline boxes when
necessary. Instead of using the PositioningContext helper methods
and we reuse the contexts between line breaks.
Fixes#25279.
Add a few helper methods which allow removing duplicate code in
PositioningContext. These methods will also be used to properly
implement hoisting in inline layout.
Do not try to read pixels from an FBO without read buffer
A follow up to #25905, this adds another check to the WebGL2 ReadPixels implementation to fix
an OpenGL invalid operation crash when the method is called on a bound framebuffer that has no read buffer.
<!-- Please describe your changes on the following line: -->

However, it seems there's an issue with the headless mode: when ReadBuffer is called on the default framebuffer with the value `GL_BACK`, like [here](e1103176e3/tests/wpt/webgl/tests/conformance2/renderbuffers/readbuffer.html (L77)), in headless mode an invalid operation is generated. In non-headless mode the whole test completes successfully:

Add support for WebGL2 read and draw buffer settings
Adds support for the `ReadBuffer` and `DrawBuffers` WebGL2 calls and the related parameter getters.

<!-- Please describe your changes on the following line: -->
This is marked as WIP because with these functions added (but apparently not directly related to them), some tests now run into states that produces crash.

Add support for launching devtools server on random port
In case the default port(6000) or the port specified by user for
devtools server is already taken, random port will be assigned to
it which is reported to the embedding layer for display to user.

layout_2020: Paint hoisted positioned fragments in tree order
Instead of painting hoisted position fragments in the order to which
they are hoisted, paint them in tree order and properly incorporate them
into the stacking context.
We do this by creating a placeholder fragment in the original tree position
of hoisted fragments. The ghost fragment contains an atomic id which
links back to the hoisted fragment in the containing block.
While building the stacking context, we keep track of containing blocks
and their children. When encountering a placeholder fragment we look at
the containing block's hoisted children in order to properly paint the
hoisted fragment.
One notable design modification in this change is that hoisted fragments
no longer need an AnonymousFragment as their parent. Instead they are
now direct children of the fragment that establishes their containing block.
