[OE-core] [PATCH V2] cmake: Add a knob for cmake VERBOSE settings

[Khem Raj]

Setting VERBOSE always, while is fine on one hand for debugging, its
coming at an expense of creating lots and lots of logs, e.g. qtwebkit
compile logs alone with VERBOSE is 163MB, there are many other large
packages which use cmake e.g. WPE, webkitgtk etc which are in same range
with out this option on, the logs reduce to 861K and also speeds up
build a notch

If user needs to disable these logs for a recipe or globally

CMAKE_VERBOSE = ""

in recipe or in global metadata e.g. local.conf
