It is rarely used and FX_RECT is the more common integer rect type.

They currently take const FX_RECT*, but the pointer is never nullptr.
Also add a comment to explain why FX_RECT is the way it is. It has the
same layout as a win32 RECT.

Because we can get the lifetime check for free if we do this. This
requires adding some "constexpr/noexcept" to UnownedPtr to make the
types line up with what span.h requires.

This CL decreases the m_iXMLPlaneSize in the CFX_XMLSyntaxParser from
32*1024 to 1024 bytes. This plane size is the size of the chunks we read
the XML file in. The issue with having a large plane size is inside the
CFX_SeekableStreamProxy::ReadString we allocate a vector of the
min(planeSize, remaining_bytes). This means, we could potentially be
allocating 32*1024 bytes to read in a single character.
For the test in the attached bug the runtime went from 12s to 25ms.
