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.

CMSIS/RTX: Patch RTX4 to preserve osThreadDef compatibility ...

mbed OS used older RTX4 version and with osThreadDef accepting only 3
parameters, to preserve compatibility we hardcode the 'instances'
parameter to 1.

Correct core RTOS sleep routine timing ...

Chrono conversions inadvertantly changed the core timed sleep routine
used by the RTOS idle to use `OsTimer::update_and_get_tick()` instead of
`OsTimer::get_tick()`.

Correct this, and expand/clarify documentation and naming to try to
prevent recurrence.

Another minor fix observed while inspecting code - `OsClock` can't just
use `milliseconds`, it should match the period of `OsTimer`, which
theoretically can be different.

RTOS: use default boot-stack-size for nRF as SoftDevice is no longer used ...

Previously we overrode nRF targets to have a larger stack
due to memory required by SoftDevice. Having deprecated SoftDevice
in favour of Cordio for BLE (#12674), such requirement does not
apply anymore.

psa: Remove MBED_SPM code ...

All MBED_SPM targets have been removed previously, via commits
5cc66282ddc6 ("PSOC6: remove PSA targets") and 115b09aba43b ("psoc6:
Remove FUTURE_SEQUANA and FUTURE_SEQUANA_M0"). Remove all the dead
MBED_SPM code, as no targets use it.

rtos: Improve CMSIS-RTOSv2 app compatibility ...

Some non-Mbed-OS, pre-existing CMSIS-RTOSv2 applications depend on
CMSIS-RTOSv2 Automatic Dynamic Allocation, also known as Object-specific
memory pools. Mbed OS doesn't by default provide any memory to the
CMSIS-RTOSv2 Automatic Dynamic Allocation pool, as doing so would waste
memory if the feature is not used; even if the feature is used, as a
platform, Mbed OS can't know how many objects of which types will be
created by an application and therefore will either waste memory or not
provide enough memory in a hard to debug manner. Portable CMSIS-RTOSv2
applications depending on CMSIS-RTOSv2 Automatic Dynamic Allocation
should instead configure the memory pools themselves, as applications
know best their memory requirements.

Add Mbed configuration options which can be used by applications to
control the amounts of memory available to the CMSIS-RTOSv2 Automatic
Dynamic Allocation subsystem. This enables portable CMSIS-RTOSv2
applications, which can run on any CMSIS-RTOSv2 OS, to be able to run on
Mbed OS as well.

RTX's configuration options for CMSIS-RTOSv2 memory are documented at
http://www.keil.com/pack/doc/CMSIS_Dev/RTOS2/html/config_rtx5.html

psa: Init IPC, Mailbox and Non-secure Interface ...

These changes are for TFM_DUALCPU and TFM_V8M platforms.
The initialization happens after mbed-os kernel is kicked off and
when the thread is up and running.

We are initializing the following for TFM_DUALCPU platforms:
* IPC Interrupts for syncing multi-core platforms.
* NS Mailbox to receive messages.
* NS interface.

We are only initializing Non-secure interface for TFM_V8M platforms.

mbed_tfm_init() in tfm_mbed_boot.c overrides the WEAK mbed_tfm_init()
for a specific platform.
