ts2Fable should generate empty param xml elements for parameters that are missing typescript comments

[baronfel]

Reecent F# compilers warn on missing param names in XML Documentation, so generated xmldocs should be exhaustive here to prevent confusion.

Here's a sample from generated vscode APIs:

    module Authentication =

        type [<AllowNullLiteral>] IExports =
            /// <summary>Register an authentication provider.
            /// 
            /// There can only be one provider per id and an error is being thrown when an id
            /// has already been used by another provider. Ids are case-sensitive.</summary>
            /// <param name="id">The unique identifier of the provider.</param>
            /// <param name="label">The human-readable name of the provider.</param>
            /// <param name="provider">The authentication provider provider.</param>
            abstract registerAuthenticationProvider: id: string * label: string * provider: AuthenticationProvider * ?options: AuthenticationProviderOptions -> Disposable

note the missing options parameter here, which causes FS3390 to be fired.

Sometimes it's even worse: not only are params missing -- but use a non-existing name:

For example:
https://github.com/microsoft/vscode/blob/ffb40deb5251a524da79cbfbdb0e16af6b658802/src/vs/vscode.d.ts#L7340-L7347
(oldUri -> source; newUri -> target)
(though it seems to at least keep the order -> might be recoverable)

Note:
Since #414 ts2fable emits a #nowarn "3390" when there are xml comments (-> disable warnings about XML comments). That was easier than fixing all xml doc issues.
(Additional to invalid or missing params, quite often transformed links (<see cref=... in F#) turn out to be invalid (point to something TypesScripty or to something external. Also there a ton of different styles for links in JS with some resulting in incorrect translations))

yeah I noticed the names as well (though truly those are bugs on the vscode side of things).
