[WGSL] Add IdentityExpression node
https://bugs.webkit.org/show_bug.cgi?id=251262
<rdar://problem/104740808>
Reviewed by Myles C. Maxfield.
Address the FIXME from IdentifierExpression by introducing an
IdentityExpression node.
This new node is a special node that does nothing but point to another
expression. It's
useful when replacing nodes, if the new node is larger than the existing node.
In which
case, an identity node can be used to point to the larger node.
