Update CameraStreamBuffering test and correct instance name
- CameraStreamBuffering test is modified to use the minimum number of
frame buffers that is required to run a camera pipeline for a single
client instead of using an arbitrarily chosen number, which may not
work for certain device implementations.
- Fix a name of v1.0 EvsManager implementation in
VtsHalEvsV1_0TargetTest.cpp
Bug: 305642713
Test: atest VtsHalEvsV1_0TargetTest and
atest VtsHalEvsV1_1TargetTest
Change-Id: Ieec986dbdf947311e0bc86871432da8a988d37ad
(cherry picked from commit 2d8834dc96bd6980fc0ab1917bf8485730e5a584)
