Release 122 of the mbed library
Changes:
- new targets - Nucleo L432KC, Beetle, Nucleo F446ZE, Nucleo L011K4
- Thread safety addition - mbed API should contain a statement about thread safety
- critical section API addition
- CAS API (core_util_atomic_incr/decr)
- DEVICE_ are generated from targets.json file, device.h deprecated
- Callback replaces FunctionPointer to provide std like interface
- mbed HAL API docs improvements
- toolchain - prexif attributes with MBED_
- add new attributes - packed, weak, forcedinline, align
- target.json - contains targets definitions
- ST - L1XX - Cube update to 1.5
- SPI clock selection fix (clock from APB domain)

- F0 - update Cube to v1.5.0
- L4 - 2 targets (L476RG/VG) CAN support
- NXP - pwm clock fix for KSDK2 MCU
- LPC2368 - remove ARM toolchain support - due to regression
- KSDK2 - fix SPI , I2C address and repeat start
- Silabs - some fixes backported from mbed 3
