Split g_ir_ffi_get_ffi_type() out from ginvoke.c

Extract a function to convert GITypeTag to ffi_type from the internals
of ginvoke.c. This will be useful in figure out structure alignment.

Also fix handling of gsize and time_t to be portable. (Add a check
to configure.ac to figure out the width of time_t.)
