[c#] Support for options (#820)

* most codegen tests pass

* add flag to indicate an interface is being generated

* Enable runtime tests

* suffix "World" to world name

* split option tests so that itt can be brought up without `result`

* add back some needed types

* tidy, revert many-arguments changes

* revert ws change

* tidy and marry up namespace changes in versions test

* use Direction over bool for import or export

remove redundant in_interface flag

* correct bool conversion

* reinstate function level bool

* reinstate function level bool
