Compatibility with Unity & Android

[AuMilliat]

Proposed modifications:
Adding Microsoft.Psi.InteropAndroid, that is a reduction of Microsoft.Psi.Interop for TCPSource/Writer with a modification of dynamic to template (crash with refecerence exception on Quest).

Microsoft.Psi project modifications:
PsiStore path need to be changed for Android and check the permission to write at application level.
KnowSerializer instance writeable to allow the addition of ‘serializer’ and public to application level.
Mutex downgrade code & Removing null check operator to be compatible with Mono & Android.

Some modifications are unnecessary (or not complete) as the first target was to use Emitters and Receivers (commit ID: 446a0fa).

Change the output of nuget packages into Builds/PsiPackages folder.

10df5c0 Merge differents modifications of Pipeline (ie CreateSynchedPipeline, switch some attributes from private to internal...) and add the RemotePipelineClockExporter/Importer components that allow to synch remote \psi applications from a dataset. (Our use case is to replay the datasets in our XR platforms).

Still 2 tests failing on my side:

• SerializationTester.BoxedTest: on Assert.AreEqual(value, value.DeepClone());, SerializationTester.cs line 1000.
• SerializationTester.DictionaryBackCompat : pass when run alone.
