cae8499179 rp i2c: clean up tx_abrt handling
Make sure we always wait for the stop bit if there's a reason to -
either because we sent one, or because there was a hardware tx abort.

1ee4bb22de embassy-rp i2c: async (non-blocking) example
Simple example exercising an mcp23017 GPIO expander, configured on
RP2040 GPIOs 14+15 (i2c1) with 8 inputs and 8 outputs. Input bit 0
controls whether to display a mcp23017 register dump.

5e2c52ee5b embassy-rp: async i2c implementation
This is an interrupt-driven async i2c master implementation. It makes as
best use of the RP2040's i2c block's fifos as possible to minimize
interrupts.

It implements embedded_hal_async::i2c for easy interop.

992: (embassy-stm32): remove flash lock/unlock public API from stm32 flash r=lulf a=MathiasKoch

Instead, perform the unlocking and locking automatically on erase and write operations.

This makes the `embedded-storage` abstraction actually useable in libraries, while still keeping the flash peripheral locked the majority of the time.

990: Small pubsub improvements r=Dirbaio a=diondokter

- Futures in pub & sub are now awaited instead of returned
- Added functions for reading how many messages are available

This helps people get better compiler diagnostics. For example, I forgot to call await on a future and the compiler didn't complain.
This also helps with making some decisions based on the state of the channels.

914: (embassy-rp): Add I2C master implementation r=Dirbaio a=MathiasKoch

This PR adds both blocking and DMA based async implementations of I2C master.

Both E-H 0.2 & E-H 1.0 abstractions are implemented as well.

### Questions & concerns:
- Do we need an I2C interrupt handler (for transfer done, abort & error handling?) (async only)
- Do we need to add some automatic attempt at unblocking an I2C bus in case of failures (see ref: 7ebfd553f3/src/i2c_dma.c (L116-L142))
- Should I add `vectored_{read, write}` implementations?
