libcamera: MappedFrameBuffer: Use typed Flags<MapModes>

Remove the need for callers to reference PROT_READ/PROT_WRITE directly
from <sys/mman.h> by instead exposing the Read/Write mapping options as
flags from the MappedFrameBuffer class itself.

While here, introduce the <stdint.h> header which is required for the
uint8_t as part of the Plane.
