[OE-core] [PATCH v3] cmake: Reduce verbosity for make invocation

[Douglas Royds]

New variable OECMAKE_VERBOSE_MAKEFILE defaults to True.

Since the dawn of time, we have set CMAKE_VERBOSE_MAKEFILE=1 (True) in cmake.bbclass.
Back in 2016, we also explicitly set VERBOSE=1 in cmake_do_compile(),
to ensure that make (and ninja) output were verbose in log.do_compile.

Setting OECMAKE_VERBOSE_MAKEFILE to False means that make (or ninja)
invocations from the command-line are non-verbose,
giving CMake's default human-readable output on the terminal instead.
The user can still invoke VERBOSE=1 make if they do want verbose output.
This has no effect on the verbose output that goes into the logs.
