This introduces a `Pender` struct with enum cases for thread-mode, interrupt-mode and custom callback executors. This avoids calls through function pointers when using only the thread or interrupt executors. Faster, and friendlier to `cargo-call-stack`. `embassy-executor` now has `arch-xxx` Cargo features to select the arch and to enable the builtin executors (thread and interrupt).
Examples using bootloader
Example for Raspberry Pi Pico demonstrating the bootloader. The example consists of application binaries, 'a' which waits for 5 seconds before flashing the 'b' binary, which blinks the LED.
NOTE: The 'b' binary does not mark the new binary as active, so if you reset the device, it will roll back to the 'a' binary before automatically updating it again.

Usage
# Flash bootloader
cargo flash --manifest-path ../../bootloader/rp/Cargo.toml --release --chip RP2040
# Build 'b'
cargo build --release --bin b
# Generate binary for 'b'
cargo objcopy --release --bin b -- -O binary b.bin
# Flash `a` (which includes b.bin)
cargo flash --release --bin a --chip RP2040
