Fix examples for embassy-executor 0.10 and update dependencies

[jerrysxie]

Update all three example workspaces (std, rt685s-evk, rt633) to work with embassy-executor 0.10.0, and update related workspace dependencies:

• Bump rust-toolchain and MSRV from 1.88 to 1.90
• Bump num_enum from 0.7.4 to 0.7.5 in workspace Cargo.toml
• Update embassy-imxrt git revision in workspace Cargo.lock
• Rename executor feature flags: arch-std -> platform-std, arch-cortex-m -> platform-cortex-m in each example Cargo.toml
• Update example Cargo.lock files to resolve embassy-executor 0.10.0
• Replace removed spawner.must_spawn(X) with spawner.spawn(X.unwrap()) across all example binaries (task functions now return Result<SpawnToken, SpawnError> and spawn() takes SpawnToken directly)
• Replace spawner.spawn(X).unwrap() with spawner.spawn(X.unwrap()) to match the new spawn() -> () return type
• Add Windows-only _DEFMT_MARKER* linker stubs in std/debug.rs to work around the MSVC linker not processing defmt's ELF linker script

Looks good, though there is a lot of overlap with this PR that went on to v0.2.0: #788

I'm not sure if this sort of duplication will result in frustrating conflicts if/when we merge v0.2.0 into main. But I suppose v0.2.0 has already diverged significantly enough that there's going to be a lot of pain regardless.

I should do a mergeback soon to undiverge v0.2.0 😩

Yeah, Billy and I discussed this and looked at the divergence. We came to the conclusion that it will be painful regardless.
