Update the spec test suite submodule (#5970)

* Update the spec test suite submodule

Delete the local copies of the relaxed-simd test suite as well as
they're now incorporated.

Closes #5914

* Remove page guards in QEMU emulation

Otherwise `(memory 0 0)` was being compiled as a static memory with huge
guards which we're trying to avoid in QEMU.
