Make STM compile again and update toolchain. (#2960)

* Make STM compile again and update toolchain. The binary is too big for the flash. WIP

* Making progress with OSFS, still WIP

* more progress, still too big. Adding RAK3172 to the equasion

* Make STM compile again and update toolchain. The binary is too big for the flash. WIP

* Making progress with OSFS, still WIP

* more progress, still too big. Adding RAK3172 to the equasion

* still too big

* minimize build

* trunk fmt

* fix a couple of symbol clashes

* trunk fmt

* down to 101% with a release vs. debug build and omitting the flash strings

* fix compilation

* fix compilation once more

* update protobufs linkage

* - Toolchain updated
- Fixed macro error

* silence compiler warning
note: do something about this assert...

* new toolkit and fix Power.cpp

* STM32WL make it fit (#4330)

* Add option to exclude I2C parts

The I2C hals and related code uses a significant amount of flash space and aren't required for a basic node.

* Add option to disable Admin and NodeInfo modules

Disabled by default in minimal build. This saves a significant amount of flash

* Disable unused hals

These use up significant flash

* Add float support for printf for debugging

Makes serial look nice for debugging

* This breaks my build for some reason

* These build flags can save a bit of flash

* Don't disable NodeInfo and Admin modules in minimal build

They fit in flash

* Don't include printf float support by default

Only useful for debugging
