windows os_mmap bh_assert FAILED: (uintptr_t)mem < INT32_MAX

after enable DEBUG, windows os_mmap get this error:

Register native, size: 32

On Windows, the flag MMAP_MAP_32BIT doesn't guarantee that we get a 0 to 2GB address. In fact, after I checked the API document of VirtualAlloc, there is no similar flag to achieve that.

In my case, modify the os_mmap function on the Windows platform to directly return null when the flags contain MMAP_MAP_32BIT.

#4119 should be able to address that issue.
