posix: deprecate SEM_VALUE_MAX and SEM_NAMELEN_MAX

Browse source 
This change deprecates CONFIG_SEM_VALUE_MAX in favour of
CONFIG_POSIX_SEM_VALUE_MAX which maps directly to
_POSIX_SEM_VALUE_MAX.

Additionally, we add the Kconfig option
CONFIG_POSIX_SEMAPHORES which maps directly to the
POSIX Option _POSIX_SEMAPHORES.

For consistence, deprecate CONFIG_SEM_NAMELEN_MAX
in favour of CONFIG_POSIX_SEM_NAMELEN_MAX.
