Modify internal GetRequiredService call of GetOutputDevice/GetClientInfo APIs

[filzrev]

This PR modify existing GetOutputDevice/ GetClientInfo extension method APIs to use build-in GetRequiredService instead of GetRequiredServiceInternal ,

Background
I want to wrap following two providers to single IServiceProvider.

1. MTP's IServiceProvider
2. Custom IServiceProvider that created by Microsoft.Extensions.Dependency.

But currently GetOutputDevice/ GetClientInfo extension method assume IServiceProvider is ServiceProvider instance.
And throw exception when using these API via wrapped IServiceProvider.

As far as I've confirmed.
GetRequiredService/GetRequiredServiceInternal APIs difference is skipInternalOnlyExtensions flag only.
And it's not affect result when resolving GetOutputDevice/ GetClientInfo.

It's unclear to me what the benefit is.

GetOutputDevice should only ever be called on MTP's service provider. It seems to me you might be calling the extension method on a different service provider implementation (the one that combines MTP and Microsoft.Extensions.Dependency). But I don't think mixing stuff that way is a good idea.

I don't think mixing stuff that way is a good idea.

I agree that it's not a good design to mix IServiceProviders.

But these extension methods are exposed as public.
So, I though it should not impose restriction unless it's not strictly required.
(Existing other public methods are using GetRequiresServide except for IOutputDevice/IClientInfo)
