vkd3d-shader/hlsl: Declare vars individually when parsing struct declarations.

Browse Source 
A struct declaration with variables is now absorbed into the 'declaration'
rule, like any other variable declaration.

A struct declaration without variables is now reduced to the
'struct_declaration_without_vars' rule.

They both are reduced to a 'declaration_statement' in the end.
