When Application Services are registered via ConventionalControllers.Create(),
their types are added to DynamicProxyIgnoreTypes, which disables the
ValidationInterceptor. The AbpValidationActionFilter only checked ModelState
(DataAnnotations), so FluentValidation rules were never executed.
Add IValidationEnabled check in AbpValidationActionFilter to call
IMethodInvocationValidator for conventional controllers, enabling
FluentValidation support without duplicating validation for regular controllers.

2. remove all rewinds related to streams; the user is the one who must ensure his streams are at the correct position when calling the api; stream rewind would exclude the ability of sending partial streams (at least skippable streams, because the tail cannot be limitted in .net core)
3. RemoteStreamContent now must get the content type associated with the stream in its constructor; it may also receive the length of the stream in a read-only form (this is because some stream classes cannot provide the length and it is provided via http headers)
4. IRemoteStreamContent should implement IDisposable to allow the auto clean up of streams (example: FileStream)
