This CL replaces usages of utils.InstallFunctions and utils.InstallGetter()
with the DEFINE_METHOD* macros that ensure that the native function is
created in proper form from the beginning. Thus the function will not
require further reconfiguring like adding a computed name or removing of
'prototype' property.

This CL is one of a series of cleanup CL which are the preliminary steps for
improving function closures creation.
