ReleaseSessionsForFabric takes CompressFabricIndex which is ambiguous

[tcarmelveilleux]

Problem

Within the SDK, FabricIndex is the only unambiguous identifier.

Many methods that emanated from FabricTableDelegate::OnFabricDeletedFromStorage(chip::CompressedFabricId compressedFabricId, chip::FabricIndex fabricIndex) perpetuated use of the compressed fabric ID, because at the bottom, we have
CASESessionManager::ReleaseSessionsForFabric(CompressedFabricId compressedFabricId);

This makes the whole process more confusing and overall muddies the water about what CompressedFabricId is for. Furthermore, CompressedFabricId is not unambiguous and this could lead to some unintended behavior.

Now that secure sessions hold their fabric index, we should be able to remove CompressedFabricId from the signatures.

Proposed Solution

• Remove compressed fabric ID from FabricTableDelegate::OnFabricDeletedFromStorage()
• Add CASESessionManager::ReleaseSessionsForFabric(FabricIndex)
• Remove CASESessionManager::ReleaseSessionsForFabric(CompressedFabricId)
• Do the necessary updates in dependencies to reflect the above.
