cmake: Add all aom_config variables to the cache.

Adding the variables to the cache allows the user running cmake
to control configuration variable values using the -D parameter
passed to cmake.

Variables set by the user are used directly unless, for example,
a failing compiler flag or feature test overrides the user's
specified value. Variables not set by the user pick up the cached
default value.
