LibWasm: Return canonical NaN for min/max/floor/ceil/truncate operations
...
Instead of returning whichever argument was NaN, return the canonical
NaN instead. The spec allows the old behavior:
"Following the recommendation that operators propagate NaN payloads
from their operands is permitted but not required."
But Chrome, Firefox and Safari do not propagate the operand payloads.
Fixes 448 WPT subtests in `wasm/core`.

LibWeb+LibWasm: Reject module instantiation with correct error type
...
The spec tells us to reject the promise with a RuntimeError instead of a
LinkError whenever the module's start function fails during module
instantiation. Fixes 1 WPT subtest in `wasm/core`.

This has come up several times during code review, so let's just enforce
it using a new clang-format 20 option.

LibWasm: Make traps hold on to externally-managed data
...
...instead of specially handling JS::Completion.
This makes it possible for LibWeb/LibJS to have full control over how
these things are made, stored, and visited (whenever).
Fixes an issue where we couldn't roundtrip a JS exception through Wasm.

LibJS: Make Completion.[[Value]] non-optional

Instead, just use js_undefined() whenever the [[Value]] field is unused.
This avoids a whole bunch of presence checks.
