vmie_mem could only be built from a path. Add a second input: an
already-open file descriptor, dup()'d internally (borrowed - the
caller's fd stays valid, core owns and closes its copy).
- vmie_mem_from_fd / vmie_mem_from_fd_segs (read-write, as the path
constructors: PROT_RW, MAP_SHARED)
- vmie_mem_from_ro_fd / vmie_mem_from_ro_fd_segs (read-only: map
PROT_READ, mark the source ro; gpa_write/gva_write return -1, every
read path is unchanged; accepts an O_RDONLY fd)
- vmie_win32_open_fd (the win32 context over an fd backing file)
Factor the mmap/validate tail and the single-low segment map out of the
path constructors into shared helpers, so the path and fd inputs go
through one mmap site and one map builder each.
