Explain how to specify download paths when using wxWebRequest

Browse source 
Add an overview paragraph explaining how to use wxWebRequest's and
wxWebEvent's IDs together to specify a request's download path before
starting it. The sample shows how to interactively prompt for local
paths once a file downloads, but not how to download a file to a
specific location without user prompting, so document how to do it.

See #22986.

Closes #23504.

The location of where files are downloaded can also be defined prior to any request
by passing unique IDs to `wxWebSession::GetDefault().CreateRequest()` and processing
them in your @c wxEVT_WEBREQUEST_STATE handler. For example, create a map of IDs with
their respective download paths prior to creating any requests. For each call to
`wxWebSession::GetDefault().CreateRequest()`, pass in the webpath to download and an ID
from your map. Then, in your @c wxEVT_WEBREQUEST_STATE handler, get the ID from the
@c wxWebRequestEvent object and look it up from your ID map. Here, you can access the
download path that you assigned to this ID and proceed to save the file to that location.
