psa: Replace Mbed PSA with TF-M ...

Add TF-M to Mbed OS, replacing the previous PSA implementation for
TF-M-capable targets. This commit adds files imported from TF-M, without
modification. The version of TF-M imported can be found in
`features/FEATURE_PSA/TARGET_TFM/VERSION.txt`.

These changes switch to TF-M as the sole PSA implementation for v8-M and
dual core targets, with TF-M running on the secure side and Mbed OS
running on the non-secure side. Single core v7-M targets will continue
to have PSA implemented via PSA emulation, implemented by Mbed OS.

Move or remove many PSA-implementing files, as PSA will be provided by
TF-M on non-single-v7-M targets. Delete any files that are not relevant
for PSA emulation mode.
 - Remove imported TF-M SPM
 - Remove Mbed SPM and tests
 - Remove Mbed-implemented PSA services and tests
 - Remove PSA_SRV_IMPL, PSA_SRV_IPC, PSA_SRV_EMUL and NSPE.
 - Replace PSA_SRV_EMUL and PSA_SRV_IMPL with MBED_PSA_SRV
 - Remove any files autogenerated by
   "tools/psa/generate_partition_code.py", which no longer exists.

Add new feature `PSA` to support PSA in Mbed OS.

Move the Mbed OS implementation of PSA services for v7-M targets (which
employ PSA emulation, and don't yet use TF-M) to
features/FEATURE_PSA/TARGET_MBED_PSA_SRV. Update the `requires`
attribute in TESTS/configs/baremetal.json to avoid breaking baremetal
testing builds.

Update .astyleignore to match new directory structure

Update Mbed TLS importer to place files into FEATURE_PSA

Create the following generic PSA targets:

* `PSA_Target` (Root level PSA generic target)
* `PSA_V7_M` (Single v7-M PSA generic target)
* `PSA_DUAL_CORE` (Dual-core PSA generic target)
* `PSA_V8_M` (v8-M PSA generic target)

Flatten MUSCA_NS and private MUSCA targets into public MUSCA targets.

Move mcuboot.bin to flat location (removing prebuilt folder)

psa: Remove PSA secure binary building tools ...

The PSA-implementing secure binary is not built using Mbed OS build
tools anymore. Instead, the TrustedFirmware-M (TF-M) build system is
used to produce the secure binary. As such, we remove PSA related hooks
from the build system, remove PSA related scripts from tools/test
folder, and also remove the psa-autogen job from travis which was
running the now unecessary and removed generate_partition_code.py.

Remove the ability to generate new PSA binaries in the old manner, where
Mbed OS implements PSA. We don't yet remove any PSA binaries or break
the currently checked-in Mbed-implemented PSA support. PSA targets
integrated in the old manner will continue working at this point.

PSA release script changes. ...

Since the offline build is made to auto-generate PSA related components
and services for Secure targets, we can change the output directory to
update the files in the respective locations.
TARGET_PSA
  --TARGET_MBED_SPM
    --COMPONENT_SPE
      psa_setup.c
  --TARGET_TFM
    --COMPONENT_SPE
      --inc
	tfm_partition_defs.inc
        tfm_partition_list.inc
        tfm_service_list.inc
        tfm_spm_signal_defs.h
  --services
    --inc
      autogen_sid.h
      mbed_spm_partitions.h

The release script is been modified to commit these files if there are
any changes detected when `--commit` argument is passed.
Cleaning of auto-generated is been removed as it uses the main directory
for its operations, but PSA auto-generation will work if any of the
service and application-based manifests are updated.

Update PSA code generator ...

Unify TF-M and Mbed-SPM code generators:
 - Unify SPM initialization logic:
   - All partitions are registered at once
   - Test partitions are guarded by #ifndef
   - Introduce single template list
 - Beatify template files and add "Autogen-do not modify" notice
Prepare for integration with mbed-os build system:
 - Generate all the files in a single place
Simplify tools/psa/release.py script
