layers:Refactor image layout verify/set

VerifyImageLayout had a side effect of setting image layout state if
the layout had not been seen by the cmd buffer. This update moves the
code to set the layout outside of the verify function and instead puts
it into new SetLayout* functions that are now called in the appropriate
PreCallRecord* functions.

Note that the previous behavior caused a side effect where layouts
could be updated even when the call down the chain did not occur.
The updated behavior will always update the layout to what is passed
as the explicit layout for any image copy operations whenever the
call down the chain is made. This is desirable b/c if the layout
didn't match the app saw the error during the Validate* portion of
the call and if they chose to ignore it then validation should
reflect the layout state of the image that was set by the call.

Since the side effect mentioned above is no longer present, this change
includes an update to InvalidImageLayout test where a second call to
vkCmdCopyImage() is made in order to actually transition the initial
image layout state so that expected errors are correct going fwd.
