Fix build breaks on file insensitive system

Current we use 'A'rmNNQuantizer name for  executable
and 'a'rmNNQuantizer as library name.
Since cmake does not allow same name for executable and library.
The old way is to use a captial letter for the executable name.
But it will create a problem on system (like macosx) that the file
system is case insensitive by default. Since it will create/overwritten
file on the same folder during the cmake build which makes build failed
when BUILD_ARMNN_QUANTIZER is enabled.

Fixed this by using ArmNNQuantizerMain as the executable
name during build, then rename it back to ArmNNQuantizer using
set_target_property OUTPUT_NAME function.
