layout: Clear non-inherited properties on anonymous block
<!-- Please describe your changes on the following line: -->
This is one of my pull requests that imlement basic flexible box layout.
This pull request adds a `modify_style_for_anonymous_flow()` function to use initial values for non-inherited properties and parent values for inherited properties as the flow style. It also set border and outline to zero and set the display property from the parameter. This function may also be reused to modify style of anonymous table object in the future.
Part of code comes from `cascade_anonymous()` from @SimonSapin .

Build geckolib with MozillaBuild on Windows
<!-- Please describe your changes on the following line: -->
Given #12319 removes the direct dependency of geckolib to gcc, geckolib is now compilable without gcc, and thus builds within MozillaBuild.
This changeset also changes the triple to use the MSVC backend rather than GNU for Windows . I'm not sure whether this change is necessary, but given we use MSVC to compile Gecko on Windows, I think we would eventually need this anyway. Triples for MinGW64 and Cygwin are unchanged, so that existing build targets should not be broken.
Servo itself is still not buildable with MozillaBuild. To make that work, some changes to mozjs are necessary as well.
It is probably worth some infra coverage to avoid regression.

Treat flex flow as block in float calculation
<!-- Please describe your changes on the following line: -->
This is on of my pull requests that implement basic flexible box layout.
Currently call `is_block_like()` on flex flow returns false. This would fix some errors in tests, for example 'flexbox-justify-content-horiz-001b.htm'.

This was making us fall in a loop where the start split was empty, but we didn't
ignore it because the current fragment had this flag, but then we treated it
differently depending on the white_space property.
Not totally sure this is the proper fix, but it makes sense to me. In case it
is:
Fixes#12369.
