Update wasi-sdk in CI to latest release
This commit updates the `wasi-sdk` download used by the `wasm32-wasi*` targets. The motivation for this commit is generally just "keep things up to date" and is not intended to cause any issues or differences from before, just a routine update.

Disable run-make/split-debuginfo test for RISC-V 64
Together with `@Hoverbear,` we've been improving the state of the riscv64gc-unknown-linux-gnu target.
This is in relation to https://github.com/rust-lang/rust/pull/125220 where `tests/ui/debuginfo/debuginfo-emit-llvm-ir-and-split-debuginfo.rs` was disabled for RISC-V 64 in that another test, `tests/run-make/split-debuginfo` also needs to be disabled due to https://github.com/llvm/llvm-project/issues/56642 and the changes made in https://github.com/rust-lang/rust/pull/120518.
This test appears to be a host test, not a target test, so it isn't seen failing in https://github.com/rust-lang/rust/pull/126641, however, we are in the process of testing host tools for riscv64-gc-unknown-linux-gnu so this test has now been noticed to be a problem.

There are some more of these, but while the code is almost always the same, I want to keep the number reasonable so my doc comments can be inspected for potential inaccuracies. Tell me if 8 is too much, I can cut this down.
