Nicholas Nethercote d7801d8f98 Bug 1249174 (part 8) - Shrink XPTInterfaceDescriptor. r=khuey.
XPTInterfaceDescriptor::num_additional_types can easily fit in 8 bits -- in
practice it doesn't exceed 20, and there's already a check in DoTypeDescriptor
that it doesn't exceed 255. This patch shrinks it and moves that check into
XPT_InterfaceDescriptorAddTypes() so that any overflow would be detected more
reliably.

On 64-bit platforms this reduces sizeof(XPTInterfaceDescriptor) from 40 to 32
and correspondingly reduces "xpti-working-set" by 16 KiB.

The patch also changes XPT_InterfaceDescriptorAddTypes() into a local function,
because it's defined and only used in xpt_struct.cpp.
