Camera: Support vendor tags from multiple providers
Different vendors could have different vendor tags.
A global vendor tag cache will store all available
vendor tag descriptors from different providers.
The cache will then be shared with each camera client.
Camera metadata will use specific vendor ids stored
in the metadata buffer to identify the correct vendor
tag provider.
Bug: 34275821
Test: adb shell /data/nativetest/cameraservice_test/cameraservice_test
--gtest_filter=CameraProviderManagerTest.MultipleVendorTagTest
Complete Camera/Camera2 CTS tests
