tools: fix SPDX identifiers

Make args_erroor less verbose. ...

This removes the arugment help from the output, making the error much
easier to find. This solves #10090.

Add utility functions and Exceptions ...

These functions will be used to handle some of the error state and
warning messages produced when the scripts attempt to select a valid
toolchain.

tools/utils: ensure default build profiles are processed first ...

The command-line argument '--profile' looks for build
profiles provided in mbed-os/tools/profiles/. If a
directory name exists in the root folder with the
same name as one of the profile names provided by
default [e.g debug/develop/release], that directory
is processed instead resulting in incorrect behavior.
Fix this behavior by processing the default profiles first.

Added flag to run_cmd Popen invocation to do default decoding

PSA SPM ...

* Intorduce PSA-SPM to mbed-os
* Add SPM tests (for PSA targets)
* Add PSA PRoT internal storage Secure implementation
* Integrate SPM into the boot proccess
* PSA manifest data generator
* Introduce PSA targets skeleton to mbed-os
* Add artifact delivery to the tools

Merge duplicate keys in JSON. ...

### Description

I would love to make this an error, but we have had a duplicate key in
`targets.json` for a while now. Instead, we're merging in a semi-smart way.
This will allow you to have things like `"target.features_add"` twice, and
both will take affect.

Change update file format to binary to all targets ...

- Change the default file format to binary for all targets, even though some targets need hex as app format, updater always needs bin for now

Enable boot-loader builds ...

To enable a boot-loader style application, override
"targets.bootloader_exec" or "targets.restrict_size" on a particular
target. These parameters are a bin or hex file, and an integer, in bytes,
respectively. If either override is present, then an application region
is created after the boot-loader region, when "targets.bootloader_exec"
is present, and before post-application, when "targets.restric_size" is
present. The size of the boot-loader region is read from the file
provided in the configuration.

Remove deprecated flags args ...

The tools will no longer accept `--cflags`, `--cppflags`, or
`--ldflags`. Instead, the ability to modify these flags is
provided by the `--profile` argument. Documentation for the
`--profile` argument may be found in
docs/Toolchain_Profiles.md

Fixing project.py -S printing problem ...

Printing too large of a string can fail in Windows, as detailed here:
https://bugs.python.org/issue11395. This works around the problem by
adding a print_large_string function that breaks up the string into
smaller pieces before printing it.

Accept profile name as well as file path for tools/make.py --profile ...

--profile can be used with just a profile name eg. default, debug as
long as <name>.json file is in default profile directory.

Force installation of dependencies in entry points

Adding concept of release versions for targets. ...

Previously, the condition for including a target in a release was decided
by a 'release' key being set to 'true' in hal/targets.json. This doesn't
have enough granularity when we release multiple versions of mbed. This PR
changes the 'release' key to an array of strings, where each member is a
version that the target supports. Currently the valid versions are '2' and
'5'.

This PR also adds more robust checking for invalid target configurations
in a release. This is enforced whenever the release list is built from the
data, preventing invalid targets from coming into the release.

Finally, it updates the build_release.py script to use the new api for
fetching release targets.
