[css-align] Simple syntax for the Alignment shorthands
Now that the issue [1] about the syntax ambiguity has been resolved we
don´t need to use the custom syntax anymore. The Alignment shorthands
use now the simple syntax, defined based on the longhands' syntax.
Since we allow all the values valid for each longhand, we'll update
in this CL the corresponding web platform tests. Additionally, this CL
updates also the shorthand serialization tests [2], which didn't
consider the new value 'legacy' for justify-items (and place-items) due
to the bug [3] Firefox still has pending to be fixed.
