mbed_minimal_putchar assumed that buffer being NULL meant that it
should print to a file. This caused a system crash when calling
snprintf with both buffer and stream set to NULL.
It is valid to call snprintf with a NULL buffer; nothing should
be outputted, but the string length should be measured.
Define copy operators public and deleted rather declaring them private
and undefined. Will give immediate compilation errors rather than
delayed linking errors.
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.

This code prevents the ARMC6 compiler/linker from removing
SUB_REALLOC/CALLOC symbols from image when LTO is enabled
Fixes below error:
L6137E: Symbol $Sub$$calloc was not preserved by the LTO codegen but is needed by the image.
In mbed_start_application() there was a code that was supposed to
set DISDEFWBUF to one when running a debug build. However, this code
was in the wrong place, as this function is only called from
bootloader.
Move the code to correct place so that standalone applications use it
as well.
For the reference of DISDEFWBUF bit, see

`SysTimer::set_wake_time` incorrectly assumed that the `SysTimer`s tick
count and the underlying HAL timer had the same zero base. This normally
holds, at least approximately, in RTOS builds where the HAL timer starts
from zero at the same time the SysTimer is initialised.
But in bare metal builds, the HAL timer could be started some time
before the SysTimer, giving a significant discrepancy.
Beyond that, there's no requirement for HAL timers to start from zero in
the spec.
Record the HAL timer start time to get the conversion right.
Adding a new target of HW development kit using [Samsung Exynos i S111](https://www.samsung.com/semiconductor/minisite/exynos/products/iot/exynos-i-s111/) module to Mbed-OS.
This will widen the HW choices of Mbed-OS enabled NB-IoT, GNSS and Security (eFuse, AES, SHA-2, PKA, Secure Storage, Security Sub-System, [PUF](https://en.wikipedia.org/wiki/Physical_unclonable_function)) modules.
