Make the assembly trimmable

[kerams]

Is your feature request related to a problem? Please describe.

Stripe.net's assembly size is around 1.2MB with the version I am referencing. Since I only use a small portion of the API (checkout creation, webhook events, ....), I enabled trimming on the assembly with <TrimmableAssembly Include="Stripe.net" />. With this I get an assembly of just 56KB, but with runtime exceptions when creating a checkout sesssion:

System.AggregateException: One or more errors occurred. (Property Get method was not found.)
 ---> System.ArgumentException: Property Get method was not found.

   at async Task<T> Stripe.Service<TEntityReturned>.RequestAsync<T>(HttpMethod, string, BaseOptions, RequestOptions, CancellationToken)

The linker obviously removes things that are vital but only accessed via reflection.

Describe the solution you'd like

Make Stripe.net linker-friendly. This will probably require DynamicallyAccessedMembers annotations in a bunch of places.

Describe alternatives you've considered

No response

Additional context

Stripe.net 39.95.0

Hi, @kerams. I think it's a very good idea. Unfortunately it involves a large amount of non-trivial work so it might take use a while to get to it.
