Dummy methods to avoid switches and casts where possible,

- GetByte() since this represents the count of parameters to a function
which of course is 0 on non-functions. formula::FormulaByteToken and ScExternal do
overload it.
- HasForceArray() since also this is only used for operators and
functions and is 0 for other tokens.
Any other non-overloaded method pops up an assertion.
