This commit adds the allow(unused) attribute to functions and constants
that are not currently used. There is one warning remaining but
https://github.com/embassy-rs/cyw43/pull/23 attempts to address that
one. The constants have been moved into a module to allow the attribute
to be applied to the module as a whole.
The motivation for this is that it will hopefully make it easier to
spot new warnings that might be introduced by new, or updated code.
972: Restructure USB crates r=Dirbaio a=Dirbaio
- Split driver from `embassy-usb` to a separate crate. This allows making breaking changes to `embassy-usb` without having to bump all the crates with driver impls, such as HALs.
- Merge classes into `embassy-usb`. Now that breaking changes to `embassy-usb` aren't that bad, having everything in a single crate is much easier.

965: (embassy-rp): add RP2040 ROM functions and intrinsics aliases r=Dirbaio a=MathiasKoch
Add RP2040 ROM functions described in section **2.8.3.1. Bootrom Functions** of https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf
Make all ROM functions (normal and floating point) provide both a direct
call that does the operation and a module with a ptr() function to get
the function pointer.
Add a feature to enable automatic caching of the result of ROM table
function lookups.
Add a check for a V2 bootrom when using floating point functions that
require it. Panic when it's not present.
Add a standardized macro for intrinsics export and connect the simple
ROM functions to intrinsics.
Direct copy from `rp-hal`! Full credit to those guys for all the heavy lifting.

960: Add non blocking Bxcan constructor r=Dirbaio a=andyblarblar
This PR adds a non-blocking constructor to the Bxcan Can wrapper struct. This allows for the creation of the Can periferal without blocking for a sync with the Can bus.

971: (embassy-boot): add blocking API to FirmwareUpdater r=lulf a=MathiasKoch
Also add a split `prepare_update` + `write_firmware` API, to allow for an optimized update API at the exchange of added complexity.
The old API is left in place to allow users to choose the complexity level that fits their needs.

961: Parameterize Signal with RawMutex r=ivmarkov a=ivmarkov
The `RawMutex` parameter is deliberately chosen to be the second one, so as it can take as a default `CriticalSectionRawMutex`. This way backwards compatibility is preserved, and users utilizing the `critical-section` crate everywhere can just continue to use the more ergonomic single-generic-parameter version of Signal.
I'm thinking we should probably do the same for `Channel`, and move the `RawMutex` parameter as the last one in the list, with a `CriticalSectionRawMutex` being its default. But that's a backwards-incompatible change of course.

This commit adds constants intended to be used with the `cmd_word`
function.
The motivation for this to (hopefully) improve the readability of the
code.
958: Implement proper `Drop` for `BufferedUarte` r=lulf a=ZoeyR
The drop method in `BufferedUarte` was prone to hanging indefinitely and also didn't actually disable the peripheral. I mostly copied over the drop method from `Uarte` with some modifications since `BufferedUarte` could have a transmit lasting indefinitely.

This commit comments out two Timer::after calls which look like they
go together with previous instructions, but those instructions are
currently commented out, so it looks like these calls are not
currently needed.
This commit adds a comment to the setting of the iovar `bus:txglom`.
The motivation for this is that I had not heard of 'glom/glomming'
before and having a comment might help others that are not familar with
the term.
