Rethink STM32 I2C v2 HAL (#78) ...

* Initial attempt at rethinking the STM32 I2C v2 HAL.  Makes single-byte work properly and adds a new 'state' variable to track what the hardware is doing.

* Fix some initial test failures

* Fix incorrect logic

* Fix more incorrect logic

* Tabs to spaces

* Fix repeated starts with single-byte API

* Fix race condition causing stop() after nacked address to sometimes break things

* Fix missed i2c structs that should have been removed

* Fix doing a repeated start from single-byte to transaction API causing I2C peripheral to lock up

* Fix xferOperation being set wrong for repeated starts, causing the peripheral to hang

* Fix race condition with repeated start after single-byte operation

* Fix compilation for targets that use I2C IP v1

* Fix initialization of XferOperation for API v1, optimize stop()

* Remove unneeded line

* Add docs for I2C events

* fix comment

Fix ASM that interfered with the GCC linker script and made the linker try to zero the entire RAM space (#75)

Fix hal-sleep-manager test on nRF52 and clean it up in general (#74)

Enable Arduino Nano 33 BLE (#55) ...

* Add upload target for Arduino Nano 33 BLE, fix linker script preprocessing, add option for USB serial by default

* astyle error

* Use HINTS instead of PATHS so that the Arduino dir is searched first

* Enable OpenOCD and PyOCD for Nano 33 BLE in SWD mode

* Fix missing dependency for USB tests on Windows

* Add RAM defines for nrf52840

* Fix mbed-storage-kv-config depending on SD card library even if said library was not enabled

* No longer need to modify linker script now that we aren't using whole-archive!

* Add OPENOCD_ADAPTER_SERIAL

* Add handling for cmsis dap

* Fix typo

* Fix weak symbol issue causing Bluetooth to not work.  In this case, the weak implementation can simply be removed, because there's no legitimate case where it is used.

Don't use whole-archive linking (#71) ...

* First attempt at converting to OBJECT libraries.  Not working due to more object library limitations

* Only compile the main libraries as OBJECT, because that's all that CMake can be made to do right now.

* Fix availability of target-specific flags

* Missed some usages

* Fix some STM32 ethernet stuff that was not linking correctly

* More fixes for STM32 ethernet and weak symbols

* Fix prebuilt object file linking for MUSCA_S1
