std: openDirAbsolute and accessAbsolute (#7082)

* add more abosolutes

* added wrong files

* adding 2 tests and changing the function signatures because of lazy analysis not checking them

* fix a bug that got uncovered by lazy eval

* Add compile error when using WASI with openDirAbsolute and accessAbsolute

* typo
