.Net: Simplify memory namespaces (#4230)

Closes task `#1` of the issue -
#3151

### Description

The `Memory` keyword is removed from the namespaces to make them
slightly shorter and aligned with AI connector namespaces:
- `Microsoft.SemanticKernel.Connectors.Memory.Chroma` ->
`Microsoft.SemanticKernel.Connectors.Chroma`
- `Microsoft.SemanticKernel.Connectors.Memory.AzureAISearch` ->
`Microsoft.SemanticKernel.Connectors.AzureAISearch`
- same for Kusto, Milvus, etc

The `MemoryBuilder`, `VolatileMemoryStore` classes that live in the
`Plugins.Memory` project under the
`Microsoft.SemanticKernel.Plugins.Memory` namespace are moved to
`Microsoft.SemanticKernel.Memory` namespace where they naturally belong
to.
