Aliaksandr Kalenik 5f74da6ae8 LibWeb: Fix "box-sizing: border-box" resolution for abspos items ...

The `calculate_inner_width()` and `calculate_inner_height()` resolve
percentage paddings using the width returned by
`containing_block_width_for()`. However, this function does not account
for grids where the containing block is defined by the grid area to
which an item belongs.

This change fixes the issue by modifying `calculate_inner_width()` and
`calculate_inner_height()` to use the already resolved paddings from the
layout state. Corresponding changes ensure that paddings are resolved
and saved in the state before box-sizing is handled.

As a side effect, this change also improves abspos layout for BFC where
now paddings are resolved using padding box of containing block instead
of content box of containing block.
