SkiaGLRE caching: monitor the caching of shaders
Bug: 178661709
Test: adb shell setprop debug.renderengine.backend skiagl
adb shell stop && adb shell start
adb shell dumpsys SurfaceFlinger
Add an implementation of PersistentCache that allows us to monitor
whether a shader was generated when we expected one to be. This can be
repurposed in the future (i.e. once we've generated all the shaders we
expect) to verify that we do *not* generate shaders after primeCache
finishes.
Add the number of recently cached shaders (i.e. since the last call, or
primeCache, if this is the first call) to the output of dumpsys.
