Add missing JSDoc classes and methods

There are some missing JSDoc methods as seen in [this report](https://github.com/dsherret/ts-morph/blob/latest/packages/ts-morph/wrapped-nodes.md).

Summary:

* JSDocAugmentsTag
* `class`
* JSDocSignature
* `typeParameters`
* `parameters`
* JSDocTypedefTag
* `fullName`
* `typeExpression`
* JSDocPropertyLikeTag - Missing methods in this mixin

Missing classes:

* JSDocAllType
* JSDocAuthorTag
* JSDocCallbackTag
* JSDocEnumTag
* JSDocNamepathType
* JSDocNamespaceDeclaration
* JSDocNonNullableType
* JSDocNullableType
* JSDocOptionalType
* JSDocTemplateTag
* JSDocThisTag
* JSDocTypeLiteral
* JSDocUnknownType
* JSDocVariadicType

This would be an easy issue for someone to implement if they feel up for it.

Start with the linked wrapped-nodes.md report and compare its missing JSDoc classes and members with the existing ts-morph API. Work through the explicitly listed classes, methods, and JSDocPropertyLikeTag mixin gaps, then verify that the report's missing entries are represented in the generated wrapper API.
