camera2 (v)ndk: Add APIs for pre-allocation of surface buffers.

Clients may need to pre-allocate stream buffers in order to reduce
affects of buffer-allocation time such as frame jank till steady state
capture is reached (eg: for a repeating request).
The SDK already has an api which does this :
CameraCaptureSession.prepare(Surface). We're exposing a similar API to
the ndk/ vndk here.

Bug: 259735869

Test: NdkCameraDeviceTest.java
