A single transition value that includes 'none' for transition-property is
valid, so we should store whole specified values (if it's valid). Whereas,
the spec [1] clearly says for the case where there are multiple entries;
If there is more than one <single-transition> in the shorthand, and any of
the transitions has none as the <single-transition-property>, then the
declaration is invalid.
'none 2s linear 2s' is a test case for the former, '1s width, 2s none' is a
test case for the latter.
Note that with this patch, 'transition: none' is serialized as 'none 0s ease 0s'
instead of 'none' but it matches Gecko.

Keep the unit of the serialization of specified::CalcLengthOrPercentage.
For the serialization of specified values of calc(), we should keep the
units of absolute lengths, so use AbsoluteLength.

This patch adds measurement of Selectors within StyleRule. This requires
exposing the pointer within ThinArc.
The patch also adds measurement of the several CssRule variants, in order to
measure nested CssRules (and PropertyDeclarationBlocks) within them:
DocumentRule, MediaRule, PageRule, SupportsRule.
We were parsing @page rules correctly and serializing for cssom when we
we need. But we weren't actually including them to the pseudo element
declarations when we need to print a page.
Reduce duplication in generated ServoComputedData::to_declaration_block.
This reduces the size of the code in libXUL by 23.4k according to bloaty.
