Remove the wrapper/coercion-passing logic for submultiplicity checks

Instead, we use a dedicated DelayedError, which is emitted
systematically on submultiplicity checks, but is suppressed if we can
indeed solve the submultiplicity constraint with a reflexivity
coercion.

This way, we don't have to return anything from `tcSubMult`, which now
looks like a regular constraint check, the rest is implementation
detail. This removes all of the strange boilerplate that I'd been
struggling with under the previous implementation. Even if
submultiplicity checks are not properly constraints, this way it's
contained entirely within a `WantedConstraint`. Much more pleasant.

Closes #25128.

user's guide: update docs for X86 CPU flags

This commit updates the section of the user's guide pertaining to
X86 feature flags with the following changes:

  - the NCG backend now supports SIMD, so remove all text
    that says the contrary,
  - the LLVM backend does not "automatically detect" features,
    so remove any text that makes that claim.

ci: RISCV64 cross-compile testing

This adds a validation job which tests that we can build a riscv64 cross
compiler and build a simple program using it. We do not currently run
the whole testsuite.

Towards #25254
