f0be2fdce4 Extend tracing api to support executor id and end task 
Allow applications to provide a trace implementation that only needs to
implement APIs used by the embassy executor, and provide more context in
the event of multiple executors being used.

executor: use WakerHack unconditionally even if nightly feature is enabled. (#3528) 
This ensures the executor compiles with all recent nightly versions,
including the stable-but-with-nightly-features-enabled xtensa rustc.

9e6e09a8d7 executor/spin: introduce an architecture agnostic executor 
Spin polls the raw executor and never sleeps. It is useful for disabling
any power features associated with wfi/wfe-like instructions.

When implementing support for the CH32V30x MCU, the wfi instruction
had issues interacting with the USB OTG peripheral and appeared to be
non-spec-compliant.

1. When sending a USB Data-in packet, the USB peripheral appears to be
unable to read the system main memory while in WFI. This manifests in
the USB peripheral sending all or partially zeroed DATA packets.
Disabling WFI works around this issue.

2. The WFI instruction does not wake up the processor when MIE is
disabled. The MCU provides a WFITOWFE bit to emulate the WFE instruction
on arm, which, when enabled, ignores the MIE and allows the processor to
wake up. This works around the non-compliant WFI implementation.

6a4ac5bd60 Add collapse_debuginfo to fmt.rs macros. 
This makes location info in defmt logs point to the code calling the macro,
instead of always to fmt.rs as before. Fix works with nightlies
starting with today's, and stable 1.81+.

3f45ec6ead use nightly waker_getters APIs 
Since https://github.com/rust-lang/rust/issues/96992 has stalled,
to prevent potential unsoundness caused by transmuting to &WakerHack,
we can use nightly waker_getters APIs by gating it behind nightly
feature in embassy-executor without waiting for it to be stablized.
