The distinction might not be worth highlighting here, but types like
size_t are a bit special in that they come from the C standards and
assumptions about them are really built into the compiler.

The system can define its own size_t, but it had better be equivalent
to the compiler's definition otherwise bad things will
happen...

Where does this arbitrary-looking list of headers come from?

>From the C standards at least, <stddef.h> seems to be the canonical
header for this type.
