Add GetDynamicAsync methods for dynamic deserialization

Added `GetDynamicAsync` methods to `ProfileApi`, `RecActionApi`,
and `ResultApi` to enable dynamic payload deserialization.
These methods support optional parameters for filtering and
are conditionally compiled for `NETFRAMEWORK` and other
frameworks, with nullable reference type support where
applicable. Internally, they reuse the existing `GetAsync<object>`
method for data retrieval.
