part 1: Move delete-before-invisible-line-break.html and forwarddelete-before-invisible-line-break.html to under `mozilla

These tests were introduced in bug 1923251 at first landing. They are for
testing the behavior when the last character before block boundary is changed
because we require a padding line break if the last character is a collapsible
white-space.

However, Chrome uses an NBSP for the last white-space and <br> does not make
the last collapsible white-space visible different from Gecko. Therefore,
Microsoft has changed the test and changed the expected results which won't test
what I'd have liked to check.

In the Chrome's behavior, they are not required, but they are important to touch
our text editing code. So, they should be under Mozilla specific directory.

layout: Implement keyword sizes for block layout heuristics

Block layout uses some heuristics to guess whether margins are separated
by clearance and then don't collapse. These heuristics now take the
min-content, max-content, fit-content and stretch sizing keywords into
account.

[SRI Message Signatures] Drop the alg parameter.

As per WICG/signature-based-sri#33, the plan
is to reject the alg parameter entirely, rather than locking it to a
single value.

layout: Fix intrinsic contributions of anonymous blocks

In order to compute the inline min-content and max-content contributions
of an anonymous block, we were finding its min-content and max-content
inline size with a SizeConstraint coming from the block size of the box.

However, anonymous blocks do not establish a containing block for their
contents, so this patch uses a SizeConstraint from the block size of the
containing block.

Block-in-inline shouldn't keep an IFC from being non-contiguous.

A block-in-inline may only contain fragmented parallel flows, for all we
know, so it cannot unconditionally count as "in-flow", since we might
fail to mark a container as potentially non-contiguous that way.

In the test included, there's a text node "x xx", where the first word
should be in the first column, and the second word should be in the
fourth. There's no room for such a wide piece of text ("xx") before
we're past the tall float.
