GH-45451: [C#] Integration with Grpc.Net.ClientFactory

[robcao]

Rationale for this change

See #45451. This adds out of the box compatibility with the Grpc.Net.ClientFactory, library, which is fairly standardized for users making gRPC requests in .NET web applications.

What changes are included in this PR?

Added a new constructor to FlightClient that accepts a CallInvoker instance.

public FlightClient(CallInvoker callInvoker)

Are these changes tested?

Yes, added a unit test to resolve an instance of the FlightClient using the Grpc.Net.ClientFactory integration and made a request with it.

Are there any user-facing changes?

Yes, a new overload constructor of FlightClient was added.
