Basic support for PROVIDE and PROVIDE_HIDDEN, currently only within SECTIONS

The existing parser does not validate expressions. To support PROVIDE(sym = expr), I implemented simple simple correctness validation based on brace counter. It aborts
reading expression tokens, if extra ')' is seen. This changed error message in one of the tests
