Math: make Color default alpha values work with Half.

There's some fugliness needed for the MSVC 2017 crash workaround but
otherwise all good.

Math: make Vector::pad() default argument work with Half.
...
Got lucky enough that the default zero-initialization constructor does
exactly what I need. Otherwise ugh I don't know what I would do.

Math: make it possible to construct Half from a double.
...
A lot of generic code uses T(1.0) and right now that caused an ambiguity
between the Float and UnsignedShort constructors.

Math: batch table-based half-float packing/unpacking.
...
It's a lot of code, but it still seems to be the fastest option of all
we have. This was the original idea when implementing half-float support
in 2016 but then I shelved it in favor of a simpler (but slower) code,
keeping the table only for the benchmark, calculated at runtime. But now
we need a batch version of this, so this comes handy.

Revert "Math: preserve signs in the Matrix[34]::scaling() getter."
...
Turns out this seriously broke properites that should always hold, such
as that R*S = M for a R and S extracted out of M. Another way to fix
this would be flipping signs in the rotation() / rotationShear() / ...
queries as well, but that adds extra operations to both rotation() and
scaling() and at that point it's just better to do what was done the
whole decade before.
To ensure this doesn't happen again and doesn't cost me a whole day of
debugging in an end-user app (SceneGraph TRS transformations got broken
because those assume that rotation() and scaling() *do* combine back,
which is a reasonable thing to assume), the docs are extended to note
this and there's an explicit test for both negative scale and large
angle corner cases as well.
