Original commit message:

    [mac][wasm] Work around MacOS 11.2 code page decommit failures

    MacOS 11.2 refuses to set "no access" permissions on memory that
    we previously used for JIT-compiled code. It is still unclear
    whether this is WAI on the part of the kernel. In the meantime,
    as a workaround, we use madvise(..., MADV_FREE_REUSABLE) instead
    of mprotect(..., NONE) when discarding code pages. This is inspired
    by what Chromium's gin platform does.

    Fixed: v8:11389
