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.

For release and develop profiles, turn on the linker's `--inline`
optimisation. This can save a couple of hundred bytes in a typical
image.
The optimisation replaces branches to small functions with the
inlined code from those functions. And it's possible that the
out-of-line functions can be eliminated.
Setting confined to release and develop builds only, as it can lead to
invalid debug information.
Display a post-build warning indicating to the user that the standard C
library was used instead of the small C library if the former is not
supported.
We disable C++ static destructors as best as possible in the various
toolchains, trying to eliminate unwanted destructor code. We don't want
to waste RAM or ROM on the C++-standard-specified behaviour of running
all statically-constructed objects' destructors in reverse order on
exit; we're never going to perform an orderly exit.
Techniques used include:
* `SingletonPtr` - makes an object be "lazily constructed" on first use,
and also eliminates its destructor. Lazy construction adds ROM+RAM
overhead.
* `__eabi_atexit` is stubbed out, preventing RAM usage by run-time
registration of static destructors.
* GCC has `exit` wrapped to kill shutdown code
* IAR has static destructors disabled in the compiler flags
Killing static destructors in the compiler is the optimum; if we only
stub out `__eabi_atexit`, the compiler is still inserting calls to it,
and referencing the destructors in those call.
Clang 8 added the compiler option `-fno-c++-static-destructors` (and the
object attributes `[[clang::no_destroy]]` and
`[[clang::always_destroy]]` for fine control).
We can hence enable that option in ARMC6 tool profiles, matching IAR.
This option appears to exist in ARM Compiler 6.11, but generates an
apparently spurious linker error about `EthernetInterface`. It works in
ARM Compiler 6.13, so this PR needs to wait until the compiler is
updated.
* Add optimised constexpr default constructor. Default construction
was previously by a heavyweight defaulted `nsapi_addr_t` parameter.
* Remove deprecated resolving constructor.
* Take `nsapi_addr_t` inputs by constant reference rather than value.
* Inline the trivial getters and setters.
* Use `unique_ptr` to manage the text buffer.
* Make `operator bool` explicit.
* Optimise some methods.
* Update to C++11 style (default initialisers, nullptr etc)
$(file > $@.in, $(filter %.o, $^)) is not supported in GNU Make 3.81.
Create the linker response file with pipe redirect from echo command.
This is tested with Cygwin make and make 3.8.1 shipped with macOS.
