Fix some build errors

Fix ABI differences between mbed-baremetal and mbed-os, remove PlatformMutex

rtos: Thread: Make stack allocation failure runtime catchable ...

When a Thread object's stack memory is not provided, its `start()`
member function dynamically allocates its stack from the heap. If
allocation fails, there is no way to catch it because
* `std::nothrow` is missing after the `new` keyword. As Mbed OS
is built with `-fno-exceptions` (C++ exceptions disabled), failed
allocation results in an unrecoverable fault.
* The attempted `nullptr` check, which doesn't work anyway due to
the first point, is an assertion instead of error returning.
Assertions should be used as a development tool to ensure code
behaves correctly. But out-of-memory is a completely valid runtime
situation.

This commit adds the missing `std::nothrow`, and makes `Thread::start()`
return `osErrorNoMemory` if allocation fails so the caller can handle
it.

Note: A case when a thread should never fail due to lack of memory
is the main thread. But the main thread's stack is a pre-allocated
array in the static memory, passed to the `Thread()` constructor
during thread creation, so it's not impacted by this change.

rtos: fix delay with 0 ...

Fixes error osErrorParameter that triggers our assert.
RTX delay ignored 0 previously, it now returns osErrorParameter instead.

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)

Mutex::unlock - decrement _count inside lock

ST boards: Fix sleep tracing ...

Prevent singleton lock if the RTOS is not yet ready.

lp_ticker is used during the RTOS initialization process.
ST lp_ticker implementation calls sleep functions
which in turn attempts to print to the console when sleep tracing
is enabled. Console initialization attempts to lock the singleton mutex.

Mutex::unlock - decrement _count inside lock ...

`Mutex::unlock` was decrementing the `_count` member after releasing
the mutex, which meant it was unprotected, exposing a race that
could corrupt the count.

This could lead to an assert in `ConditionVariable::wait`, which
checks that the mutex count is one.

rtos: do not include RTE_Component header ...

RTE_Component can't be included in the assembly file, as it is application header file
(C/C++) therefore assembler fails in this case. If the symbol RTE_CMSIS_RTOS2_RTX5_ARMV8M_NS is
needed, just define it via config. Therefore I am leaving the rest of ifdef _RTE_ there.

CMSIS/RTX: Pre-processor defines used for assembly ...

CMSIS repo does not support pre-processor defines, hence multiple assembly

Mbed OS tools support assembly file pre-processing, but the build system
does not support multiple assembly files for each target, hence updating
the assembly files.

1. Patch RTX so irq_cm4f.S files work with no FPU targets
2. Patch RTX so irq_armv8mml.S files to work with and without FPU
2. Patch RTX so irq_armv8mml.S and irq_armv8mbl.S files to work with secure and
   non-secure builds

CMSIS/RTX: Move Idle and Timer thread stack to bss section. ...

In case of ARM compiler, idle and timer thread stack though assigned
to `.bss.os` section since not zero initialized are part of `data` section.

In this commit, we are moving stacks of idle and timer thread to bss
section and thereby saving ROM space.
