LibPDF: Replace Value class by AK::Variant
...
This decreases the memory consumption by LibPDF by 4 bytes per Value,
compensating exactly for the increase in an earlier commit. :^)

LibPDF: Add support for the CalRGB ColorSpace
...
This isn't tested all that well, as the PDF I am testing with only uses
it for black (which is trivial). It can be tested further when LibPDF
is able to process more complex PDFs that actually use this color space
non-trivially.

LibPDF: Split ColorSpace into a different class for each color space
...
While unnecessary at the moment, this will allow for more fine-grained
control when complex color spaces get added.

LibPDF: Add a very poor path clipping implementation
...
This completely ignores the actual path and just uses its bounding box,
since our painter doesn't support clipping to paths.

LibPDF: Add a bitmap renderer
...
This commit adds the Renderer class, which is responsible for rendering
a page into a Gfx::Bitmap. There are many improvements to make here,
but this is a great start!
