Log:
[WebAssembly] Define a custom segment type for function definitions.

Since function definitions are not loaded into the address space, PT_LOAD is
inappropriate. PT_WEBASSEMBLY_FUNCTIONS is used to identify where the function
definitions are so that they can be processed at program startup time.
