feat(jsii-spec): Model parameter optionality (#432)

Method `Parameters`, `Properties` and method return types
now carry an `optional` flag that indicates whether they are
optional or required, and the `TypeReference#optional` field
was removed.

BREAKING CHANGE: JSII assemblies generated by older versions of the tool
will fail loading with this new version, and vice-versa. Re-compile your
projects in order to fix this.

Fixes #296
Fixes #414
