hwc3: Make the ComposerCommandEngine as local variable

A race condition exists because HWC uses only one
ComposerCommandEngine::Writer for all displays.
The writer takes responsibility to package AIDL functions’ return
values and deliver the package to SF. When a thread is packaging
the return value of the inner display by Writer, another
thread may call Writer::reset() for the outer display.

Test: switch applications
