to_px() usage should be avoided because it might leak saturated

e25b1f76e1 LibWeb: Forbid usage of indefinite width in calculate_min{max}_height 
Changing `calculate_min_content_heigh()` and
`calculate_min_content_heigh()` to accept width as `CSSPixels`, instead
of `AvailableSize` that might be indefinite, makes it more explicit
that width is supposed to be known by the time height is measured.

This change has a bit of collateral damage which is rows height
calculation regression in `table/inline-table-width` that worked before
by accident.

0b2da4f8c6 LibWeb: Add the default user agent MathML stylesheet 
We now apply MathML's default user agent style sheet along with other
default styles. This sheet is not mixed in with the other styles in
CSS/Default.css because it is a namespaced stylesheet and so has to
be its own sheet.

a9620d8784 LibWeb: Implement the :target selector pseudo-class 
We don't yet set the Document's target element in most cases, so this
does not function very well. But that will improve once we *do* set it,
which involves a more complete Navigables implementation.

9101c8d079 LibWeb: Use available space to resolve table container width 
Using avilable space directly while resolving table container width
allows to avoid assigning it to table wrapper box content width which
sometimes involves infinite (saturated) values.

Also this allows to get rid of set_max_content_width() which is a hack
that allows to bypass set_content_width() to assign infinite
(saturated) width to a box.

Returning greatest_child_width() from automatic_content_width() in BFC
if root box children are inline and there are min/max-width that caused
width to be changed after IFC layout while content_width should be
always set to correct value by layout_inline_children() regardless of
layout mode.

22a858a0cb LibWeb: Don't parse inline style sheets during HTML fragment parsing 
Some websites (like Reddit) like to instantiate "components" by setting
innerHTML to a huge chunk of stuff. Sometimes those huge chunks of stuff
contain inline style sheets (i.e `<style>` elements).

Before this change, we would end up parsing the CSS in those elements
multiple times, because we had no way of knowing that we were within
a fragment parser's temporary document.

This patch avoids the extra CSS parsing work by adding adding a flag to
Document that tells us it's being used by the fragment parser. Then, we
simply avoid parsing CSS for style elements in such documents. The CSS
then gets parsed immediately upon insertion into the proper DOM.
