embedded-hal SpiDevice on all esp32 variants (#106)
* WIP: common/spi: Implement `SpiDevice`

to get shared access to an SPI bus directly via the HAL.

* WIP: common/spi: add SpiBusDevice::new

to create instances via a function call.

* esp32/examples: Add example for spi device trait

* common/spi: Finish "SpiDevice" implementation

for esp32. Abandons the approach of having the user pass in some generic
mutex in favor of creating the Mutex as part of the API so it isn't
exposed to the user in the first place.

* common/spi: Add more thorough docs

* esp32/examples: Fix example for eh1 "SpiDevice"

* common/spi: Implement `SpiDevice` for xtensa arch

and move the code into a submodule that is fenced with conditional
compilation directives.

* esp32/examples: Update spi device example

to the changed APIs for the timers and clocks, and add more transmission
tests to the example code.

* common/spi: Create devices from buscontroller

directly, instead of offering only the `new` method.

* common/spi: Finish `SpiBusDevice` trait

from embedded-hal 1.0.0-alpha.8.

* esp32: Update `SpiBusDevice` usage example.

* common/spi: Fix mutex types for xtensa32 esp

because the esp32/esp32s3 can use `SpinLockMutex`, whereas the esp32s2
has access only to `CriticalSectionMutex`.

* common/spi: Implement `SpiBusDevice` for riscv

based esp32c3.

* general: Add examples for spi device loopback

to all esp variants.

* common: Use esp_backtrace in spi_eh1_device examples

* common/spi: Update module documentation.

* common/spi: Use `critical_section::Mutex`

to unify locking across all esp variants.

* esp32c3-hal: Fix spi device example

* esp32c3/examples: Fix typo in used spi pins

SPI: Implement more SPI traits from embedded-hal 1.0.0-alpha.8 (#101)
* common/spi: Turn fifo size into const

instead of hard-coding it into the code in various places.

* common/spi: Alias `write_bytes` to `send_bytes`

since they share the same interface and the same code anyway.

* common/spi: Implement `read_bytes`

as counterpart to `send_bytes` that is responsible only for reading
bytes received via SPI.

* common/spi: Rewrite `transfer`

to use `send_bytes` and `read_bytes` under the hood and remove duplicate
code.

* common/spi: Create submodule for embedded_hal_1

that is re-exported when the `eh1` feature flag is active. This removes
lots of duplicate `#[cfg(...)]` macros previously part of the code.

* common/spi: Implement `SpiBus` and `SpiBusWrite`

traits from the `embedded-hal 1.0.0-alpha.8`.

* common/spi: Make `mosi` pin optional

* esp32-hal: Add new SPI example with `eh1` traits

* esp32-hal/examples/spi_eh1: Add huge transfer

and bump the SPI speed to 1 MHz.

* common/spi: Apply rustfmt

* common/spi: Use `memcpy` to read from registers

This cuts down the time between consecutive transfers from about 2 ms
to less than 1 ms.

* WIP: common/spi: Use `ptr::copy` to fill write FIFO

cutting down the time between transfers from just below 1 ms to ~370 us.

The implementation is currently broken in that it will always fill the
entire FIFO from the input it is given, even if that isn't FIFO-sized...

* common/spi: Add more documentation

* esp32/examples/spi_eh1: Fix `transfer_in_place`

* esp32/examples/spi_eh1: Add conditional compile

and compile a dummy instead when the "eh1" feature isn't present.

* esp32-hal: Ignore spi_eh1 example

in normal builds, where the feature flag "eh1" isn't given. Building the
example directly via `cargo build --example spi_eh1_loopback` will now
print an error that this requires a feature flag to be active.

* common/spi: Use `write_bytes`

and drop `send_bytes` instead. Previoulsy, both served the same purpose,
but `send_bytes` was introduced more recently and is hence less likely
to cause breaking changes in existing code.

* common/spi: Fix mosi pin setup

* Add SPI examples with ehal 1.0.0-alpha8 traits

to all targets.

* common/spi: Fix `read` behavior

The previous `read` implementation would only read the contents of the
SPI receive FIFO and return that as data. However, the `SpiBusRead`
trait defines that while reading, bytes should be written out to the bus
(Because SPI is transactional, without writing nothing can be read).

Reimplements the `embedded-hal` traits to correctly implement this
behavior.

* common/spi: Use full FIFO size on all variants

All esp variants except for the esp32s2 have a 64 byte FIFO, whereas the
esp32s2 has a 72 byte FIFO.

* common/spi: Use common pad byte for empty writes

* common/spi: Fix reading bytes from FIFO

by reverting to the old method of reading 32 bytes at a time and
assembling the return buffer from that. It turns out that the previous
`core::slice::from_raw_parts()` doesn't work for the esp32s2 and esp32s3
variants, returning bogus data even though the correct data is present
in the registers.

* common/spi: Fix typos

* examples: Fix spi_eh1_loopback examples

RISCV vectored interrupts (#118)
* RISCV interrupt vectoring

- Adds support for vectoring peripheral interrupts to PAC handlers
- Currently supports level interrupts with priorities from 1-15
- Updated the gpio interrupt example to reflect the new changes

* remove .vscode files

* Support vectored edge interrupts

This is as simple as making sure we clear the CPU interrupt whenever we
receive one. This also documents further what APIs are safe to call when
the `vectored` feature is enabled.

* fix all examples to use vectoring

* doc & cleanup

* run handlers from ram

* make xtensa::interrupt::vectored private, we rexport public items

* fix default handlers

* pass interrupt into EspDefaultHandler
