mash: Move tray_constants.h and FixedSizedImageView to //ash/common

mash: Move tray_constants.h and FixedSizedImageView to //ash/common

These are dependencies of TrayUpdate, which I am moving to //ash/common

TBR because this is a purely mechanical move:
* move_source_file.py ash/system/tray/tray_constants.h ash/common/system/tray/
* move_source_file.py ash/system/tray/tray_constants.cc ash/common/system/tray/
* move_source_file.py ash/system/tray/fixed_sized_image_view.h ash/common/system/tray/
* move_source_file.py ash/system/tray/fixed_sized_image_view.cc ash/common/system/tray/
