ui: refactor using a common qemu_pixman_shareable
...
Use a common shareable type for win32 & unix, and helper functions.
This simplify the code as it avoids a lot of #ifdef'ery.
Note: if it helps review, commits could be reordered to introduce the
common type before introducing shareable memory for unix.

ui/surface: allocate shared memory on !win32
...
Use qemu_memfd_alloc() to allocate the display surface memory, which
will fallback on tmpfile/mmap() on systems without memfd, and allow to
share the display with other processes.
This is similar to how display memory is allocated on win32 since commit

ui+display: rename is_buffer_shared() -> surface_is_allocated()
...
Boolean return value is reversed, to align with QEMU_ALLOCATED_FLAG, so
all callers must be adapted. Also rename share_surface variable in
vga_draw_graphic() to reduce confusion.
No functional change.
