Subject: [PATCH] SurfaceFlingerPerfTests: Buffer clean up for
 SurfaceFlingerPerfTests.

Added freeBuffers() function which will be called at the end of tests. It destroys all buffers in queue instead of waiting for GC to clean up.

Test: atest SurfaceFlingerPerfTests
Bug: b/230039226
Change-Id: I28e280b8df2d7140fb51fb05fd4e897e23478143
