Targets that use TF-M for their PSA implementation are not compatible
with exporters at this time. Explicitly block use of exporters with TF-M
using targets, for better error messages.

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.

Remove PSA v8-M S target binaries will be built outside of Mbed OS and
added in as binaries which NS targets consume. Mbed OS no longer
implements PSA for v8-M targets, so there is no reason for it to build
PSA S targets.

Musca-B1 is a Cortex-M33 based target with security extension enabled.
- ARM_MUSCA_B1 is the non-secure target running mbed-os.
- ARM_MUSCA_B1_S is the secure target running TF-M.
- TF-M sources were imported and patched in previous commits.
- TF-M secure bootloader (McuBoot) for MUSCA_B1 is submitted by a
pre-built binary.
- A post-build hook concatenates The secure and non-secure binaries,
signs it and then concatenates the bootloader with the signed binary.

Support secure/non-secure combined build for non-PSA target:
1. In secure post-build, deliver built secure image to TARGET_NU_PREBUILD_SECURE
directory which is to combine later.
2. In non-secure post-build, merge non-secure image with secure image saved in
TARGET_NU_PREBUILD_SECURE directory.
3. In non-secure post-build, user can also drop pre-built secure image saved in
TARGET_NU_PREBUILD_SECURE directory and provide its own by adding the line below
in mbed_app.json:
"target.extra_labels_remove": ["NU_PREBUILD_SECURE"]
Musca-A1 is a Cortex-M33 based target with security extension enabled.
- ARM_MUSCA_A1 is the non-secure target running mbed-os.
- ARM_MUSCA_A1_S is the secure target running TF-M.
- TF-M sources were imported and patched in previous commits.
- TF-M secure bootloader (McuBoot) for MUSCA_A1 is submitted by a pre-built binary.
- A post-build hook concatenates The secure and non-secure binaries,
signs it and then concatenates the bootloader with the signed binary.
Change the heuristic for selection of CMSE in the tools python, so that
a non-TrustZone ARMv8 build can happen.
Ideally we would have more direct flagging in the targets, but this
refines the heuristic so the necessary behaviour can be easily
achieved.
* DOMAIN_NS=1 is based purely on the `-NS` suffix on the core name.
* Enabling CMSE in the compiler and outputting a secure import library
is now enabled when the core doesn't have an `-NS` suffix by either
the target label `TFM` being present or the flag `trustzone` being set.
This covers the existing ARMv8-M behaviour - TF-M builds have the TFM
label, as per its documentation; M2351 secure builds have no explicit
flagging, so we ensure that the M2351_NS target has the trustzone flag
set, and the out-of-tree secure target inherits that.
PSA code generation will be called automatically upon mbed invocation.
The autogenerated files will be created under <mbed-os-root>/PSA_AUTOGEN directory.
The "hook tools" were capable of hooking into many commands run by the build system.
To my knowlage, the only hook is the "post-build-hook". The post build hook could be
easier to reason about if the implementation is specialized for just post-build
hooking.
This commit make it much easier to point out where post build hooks are called by
making the call explicit.
