Run rust tests from wasi-testsuite

Currently can't merge this due to a failing test on android, ubuntu 22.04:

fd_filestat_get

I can reproduce it locally on OSX but I'm not completely sure I understand if the test is correct.

Also the following rust tests are failing on nightly (can't reproduce locally):

interesting_paths
close_preopen.

Will need to investigate more to figure out why these are failing.

Please see the related conversation in WebAssembly/wasi-testsuite#59. Depending on the result of that, we'll either delete the test or update the specification (and WAMR implementation accordingly).

I've raised a PR in wasi-testsuite to fix the tests which had various permissions issues etc.

posix.c change seems too big to sneak within a "Run rust tests from wasi-testsuite" PR.
i'd suggest to make it a separate PR.

Hey, thanks for the suggestion. I've made the minimum required changes to get the additional rust WASI tests to pass. Without those changes, the PR will not pass in CI so it won't be possible to split the posix.c changes into a separate PR.

Since some of the tests have changed the expected behavior (e.g. the close_preopen test previously expected closing preopens to fail but the latest version of the test expects it to succeed) it's also not possible to change the posix.c implementation without updating the wasi test commit.

The changes mainly concern behaviour around preopens but please let me know if the motivation behind any of the other changes is unclear.

edit: sorry I forgot we weren't running the rust tests at all before this change so we can split out the posix.c changes into a separate PR. I've raised

#2578
#2579
#2580
#2581

for the posix.c changes. Hopefully it will be easier to review.

After those are merged and this PR is rebased, it should be green and good to merge.

failing wasi-threads tests should pass if you rebase. cf. #2568

@wenyongh would you mind taking another look? Build is green now so should be good to merge, thanks very much.
