Rename MallocSpan<..., Mmap> to MmapSpan
https://bugs.webkit.org/show_bug.cgi?id=303091
rdar://165397945
Reviewed by Ben Nham.
MallocSpan<..., Mmap> doesn't support the interface exposed by
MallocSpan. To fix this, extract the common functionality between
MallocSpan<..., XXX> for any XXX to AllocSpanMixin<T>.
Add explicit MmapSpan to that has unambiguous mmap-related constructors.
The common AllocSpanMixin<T> will be used to implement Cocoa-specific
VMAllocSpan in the future. The upcoming VMAllocSpan will be used in
SharedMemory. This feature is needed to hold memory-owning spans that
originate from IPC or files but do not reserve handles.
