Brian Osman c021360a88 Only include one variable per declaration statement
This removes VarDeclarationsStatement entirely. VarDeclaration instances
appear directly as statements in Programs. SkSL that declares multiple
variables in a single declaration is transformed to represent that as a
series of VarDeclaration statements.

Similarly, global variable declarations are represented by
GlobalVarDeclaration program elements, one per variable.
