posix: timers: deprecate CONFIG_POSIX_CLOCK and TIMER

Browse source 
The POSIX_CLOCK option does not correspond to any standard
option. It was used to active features of several distinct
POSIX Options and Option Groups, which complicated API and
application configuration as a result.

POSIX_CLOCK is being deprecated in order to ensure that Zephyr's
POSIX Kconfig variables correspond to those defined in the
specification, as of IEEE 1003.1-2017.

Additionally, CONFIG_TIMER is being deprecated because it does
not match the corresponding POSIX Option (_POSIX_TIMERS).

With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":

* CONFIG_POSIX_TIMERS

Similarly, we introduce the following Kconfig options that
map directly to standard POSIX Options by simply removing
"CONFIG":

* CONFIG_POSIX_CLOCK_SELECTION
* CONFIG_POSIX_CPUTIME
* CONFIG_POSIX_DELAYTIMER_MAX
* CONFIG_POSIX_MONOTONIC_CLOCK
* CONFIG_POSIX_TIMEOUTS
* CONFIG_POSIX_TIMER_MAX

In order to maintain parity with the current feature set, we
introduce the following Kconfig options that map directly to
standard POSIX Option Groups by simply removing "CONFIG_":

* CONFIG_POSIX_MULTI_PROCESS - sleep()

Similarly, in order to maintain parity with the current feature
set, we introduce the following additional Kconfig options that
map directly to standard POSIX Options by simply removing
"CONFIG":

* CONFIG_XSI_SINGLE_PROCESS - gettimeofday()
