Skip f32.wast etc. on linux due to Alpine-x86_64 issue + add CI testi…

…ng (#8558)

This was noticed during creating the 129 release:
#8557 (comment)

Add an alpine build to CI for x86_64, mirroring our release builds, so
we do not lack coverage (which led to the issue only showing on release, not
CI).

Also make the alpine CI build identical to alpine release (copied from
`create_release`).

Version 125 (#8063)

Version 124 (#7874)

We support a lot of new features in this one...

Release version 123 (#7394)

Given the big speedup in our official release binaries for Linux, this
seems useful to get to users quickly.
