Xi Ge d927852541 libSyntax: generate condition checking code for node choices instead of hard-coding them. NFC (#13583) ...

This patch adds a python function to syntax node gyb support called
"check_child_condition". Given a child's definition, this function
generate a C++ closure to check whether a given syntax node can satisfy
the condition of the child node. This function recursively generates code
for node choices too, therefore we don't need to hard code the
condition checking for node choices.
