1004: Fix internal channels for adc v2 r=lulf a=chemicstry
Internal channel reading was broken on adc_v2, because `Adc::read()` requires gpio pin trait, which was not implemented by `VrefInt`, `Temperature`, `Vbat`. The required configuration bits `tsvrefe`, `vbate` were not enabled either. This PR makes it a bit closer to how adc_v4 works.
While at it, I also changed adc_v2 to use `RccPeripheral` instead of permanently enabling all ADCs.

1003: all Cargo.toml: Add license to all crate Cargo.toml files r=lulf a=chrysn
This sets the license to "MIT OR Apache-2.0" in a machine readable form on all crates, as it was already in human readable form in the README.md file, and reaffirmed in #1002.
(The statements on all the individual examples might not be strictly essential for the `cargo deny` use case as they are leaf crates, but other tools might use that information).

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?
