[TO-DROP] build: add MSAL single file publish workaround

TODO: IS THIS STILL NEEDED?

Add a workaround for a bug in MSAL's loading of native dependencies when
published as a single file bundle.

Using the IncludeAddContentForSelfExtract option will cause all managed
and native dependencies to be extracted on first launch to a temporary
directory, and executed from there.

This only affects Windows as only Windows has support for the MSAL
runtime that requires the native dependencies.

+      The Microsoft.Identity.Client.NativeInterop.dll assembly is not able to
+      locate the native libraries when published as a single file and crashes.
+      This is due to the use of an unsupported API (Assembly::CodeBase).

+      the cost of decompressing the assemblies is only paid on the first launch.
