chore: add wasmtime install script and hook it on CI

[kostasrim]

• add tools/install_wasmtime.sh script
• install wasmtime on CI

So we need a couple of more things here and I will pause this as there are other priorities atm.

1. There was an issue compiling search_family_test which caused the linker to complain on zstd lib. Reordering the linking order fixed it (this is already done here)
2. There is an issue with alpine builds because they removed the lfs64 (large file support) variant and the linker will fail to recognize them so the CI will fail (TODO)
3. Extend install script to include arm such that we can use it in our reg tests (TODO)

Not sure, we fetch 3rd party libraries from bundled releases with cmake. We can do the same here
