random: Restructure RANDOM Kconfig 



Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu.  Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom.  Do not present pseudo generators if a true random generator
is presented.

This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.

In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.

Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.
