This commit allows to add a Makefile.dep file in an application
directory to finely tune application dependencies, based on the
used TOOLCHAIN.
Using this mechanism, if an application has dependencies pulled-in based
on the TOOLCHAIN, info-boards-supported, will take this into account to
determine the boards supported by an application
This commit introduces a common storage backend for SUIT manifest
payloads. Different backends can be compiled into a single firmware.
Degending on the component name in the SUIT manifest, a storage backend
is selected by the parser.
For an app, a user usually uses `gnrc_ipv6_router_default` to activate
routing behavior. `gnrc_sixlowpan_router_default` is used by that to
pull in further dependencies for 6LoWPAN routers. It shouldn't pull in
`gnrc_ipv6_router_default` again, as this introduces a cyclic
dependency.
It has no real purpose other than pulling in `gnrc_ipv6_router` as a
dependency, which is already done in other places (or by pulling in its
dependencies).
Just because a user pulls in the DNS client (`sock_dns`) doesn't mean
they want to pull in RDNSS option support as well. Besides, since
`gnrc_ipv6_nib_dns` depends on `gnrc_ipv6_nib`, this forms a circular
dependency that really isn't necessary.
Support for picolibc as alternative libc implementation is added with
this commit. For now only cortex-m CPU's are supported.

squash fixes in
v3:
Remove picolibc integer printf/scanf stuff from sys/Makefile.include,
it gets set in makefiles/libc/picolibc.mk
fixup for dependency
It is desireable to have a way to identify network devices.
This should be independent from the type of netdev, so a common identifier is needed.
Base this on the driver ID and the index in the configuration struct.
This way we achive unique IDs that stay consistent for any firmware flashed on a board.
- Add libstdcpp feature to indicate a platform is providing a libstdc++
implementation ready for use
- The existing cpp feature now only indicates a working C++ toolchain without
libstdc++. (E.g. still useful for the Arduino compatibility layer.)
- Added libstdcpp as required feature were needed
- Added some documentation on C++ on RIOT
