fix: ensure the typescript definitions only export correct value types (#28712 )

* fix: ensure the typescript definitions only export correct value types

In typescript there are two main types of "types" you can export, value types (class, const) and definition types (type, interface).  The typescript compiler will let anything declared via const or class be used as a value.  Unfortunately we were exporting a bunch of things (see the diff) as class/const when they weren't actually exported values. This lead to typescript being happy but the runtime throwing errors (not something we want).

This change passes "exported-in" context through our docs, to the parser and then to the definitions generator to ensure we only mark things as exported in the ts defs that we actually export.

Fixes #22167

* chore: update typescript-defs

* chore: update typescript-defs

* chore: fix bad typescript in IPC test

* docs: test rendering of new syntax

* chore: update per feedback, use same syntax but with 'this is not exportedd' line

Class: IncomingMessage

Handle responses to HTTP/HTTPS requests.

Process: Main
This class is not exported from the 'electron' module. It is only available as a return value of other methods in the Electron API.

IncomingMessage implements the Readable Stream interface and is therefore an EventEmitter.

Instance Events

Event: 'data'

Returns:

chunk Buffer - A chunk of response body's data.

The data event is the usual method of transferring response data into applicative code.

Event: 'end'

Indicates that response body has ended. Must be placed before 'data' event.

Event: 'aborted'

Emitted when a request has been canceled during an ongoing HTTP transaction.

Event: 'error'

Returns:

error Error - Typically holds an error string identifying failure root cause.

Emitted when an error was encountered while streaming response data events. For instance, if the server closes the underlying while the response is still streaming, an error event will be emitted on the response object and a close event will subsequently follow on the request object.

Instance Properties

An IncomingMessage instance has the following readable properties:

`response.statusCode`

An Integer indicating the HTTP response status code.

`response.statusMessage`

A String representing the HTTP status message.

`response.headers`

A Record<string, string | string[]> representing the HTTP response headers. The headers object is formatted as follows:

All header names are lowercased.
Duplicates of age, authorization, content-length, content-type, etag, expires, from, host, if-modified-since, if-unmodified-since, last-modified, location, max-forwards, proxy-authorization, referer, retry-after, server, or user-agent are discarded.
set-cookie is always an array. Duplicates are added to the array.
For duplicate cookie headers, the values are joined together with '; '.
For all other headers, the values are joined together with ', '.

`response.httpVersion`

A String indicating the HTTP protocol version number. Typical values are '1.0' or '1.1'. Additionally httpVersionMajor and httpVersionMinor are two Integer-valued readable properties that return respectively the HTTP major and minor version numbers.

`response.httpVersionMajor`

An Integer indicating the HTTP protocol major version number.

`response.httpVersionMinor`

An Integer indicating the HTTP protocol minor version number.
