[Feature Request] Send minimal server side telemetry

Is your feature request related to a problem? Please describe.
Being able to send the sku (MsIdWeb) and version in requests to EVO so that we can measure the usage of Microsoft.Identity.Web and proactively contact 1P.

We want to know:

• when MSAL makes a call is it initiated by Microsoft.Identity.Web ?
• when Wilson makes a call, is it initiated by Microsoft.Identity.Web?

Today:

• MSAL.NET will send x-client-sku: MSAL.NetCore (and x-client-ver the version)
• ASP.NET Core will send x-client-sku: ID_NETSTANDARD2.0 (and x-client-ver the version)

We don't want to lose this information.

Therefore, given that Microsoft.Identity.Web acts as an orchestrator, the best is, as @jennyf19 suggested a few weeks ago, to add other properties in addition to the ones we have already.
x-client-orch: ID_WEB
x-client-orch-ver: (Microsoft.Identity.Web version from the assembly).

Warning: MSAL sku should not be changed (features are available based on SKU and version)

@jmprieur to clarify expectations here.
