This adds a wazero adapter which passes wasi-testsuite 100pct on darwin, linux and windows. While the main change was adding inodes to the wasi `fd_readdir` dirents, there was a lot of incidental work needed. Most of the work was troubleshooting in nature, around windows specifically, but also wrapping of files. This backfills a lot of tests and reworked how wrapping works, particularly around windows. To accommodate this, we drop `os.File` special casing except for `sysfs.DirFS` Signed-off-by: Adrian Cole <adrian@tetrate.io>
