Support more top-level primary expressions
This change allows numbers and literals to be used as top-level primary
expressions without failing:
1> xmerl_xpath:string("3", Doc).
#xmlObj{type = number,value = 3}
2> xmerl_xpath:string("'foo'", Doc).
#xmlObj{type = string,value = "foo"}
We still need to allow arithmetic, comparative, boolean and negative
expressions, as in `xmerl_xpath_pred:expr/2`.
