Option settings and checks are mixed in config_<component>.h.
config_<component>.h is then included by other components outside the
current one.
Those checks often depends on build options managed in CMake/Kconfig
config. Many of these build options are transparent to other components.
For example, if a <component> specific build option is transparent to
NSPE, when NS is built separatedly from TF-M secure side, this build
option is missing in NS build and then the corresponding checks in
config_<component>.h will fail the build.

Decouple option settings and checks to solve the issue above.
- Add #ifndef/#endif pairs in config_base.h to collect all the base
  option settings.
- Let config_tfm.h include config_base.h. It becomes the common config
  header file to be included by all components.
- Only keep invalid config check in config_<component>.h. Renamed
  config_<component>.h as config_<component>_check.h.
  Users shall explicitly set config values in PROJECT_CONFIG_HEADER_FILE
  rather than relying on components to implicitly set default values.
- config_<component>_check.h is only included by <component> for check
  only.

rt_main is an unnecessary layer that can be removed. Instead partition
entry point function can be called directly.
This simplifies the code and enables passing a parameter to the thread
using register r0. Previously passing parameter using r0 was impossible
because rt_main used r0.

The Kconfig tool now supports loading config files and merging them
into one. The merging is basically done by the later loaded config files
overriding the first loaded config files with dependencies respected.

With this feature, the Kconfig system will be aware of the configs such
as platform settings and profile settings rather than having default
values for all configurations.

The environment variables are for the Kconfig files which refer to env.
variables, for example the PLATFORM_PATH.
Now the PLATFORM_PATH is no longer passed as one of the arguments, it's
done via the --env argument now. Of course, any other env. variables can
be appended at will.

The previous PSA API redirecting is statically performed in header
files, based on C preprocessors exported by the configuration system.
The C preprocessors make the configuration maintenance harder, and
users could not find the exact PSA API name in debug symbols, which
is confusing.

Now the redirecting turns into a runtime behavior. SPRTL calls
corresponded ABI for PSA API. The ABI is set in the Secure Partition
local storage by SPM when booting, based on Secure Partition types.
Check 'prv_process_metadata' and 'psa_api_ipc.c' for details.
