Move two more functions to dwarf2/leb.h

This moves read_n_bytes and read_direct_string to be with the the
low-level value-reading code.

2020-02-08  Tom Tromey  <tom@tromey.com>

	* dwarf2/read.c (read_n_bytes, read_direct_string): Move to
	read.c.
	* dwarf2/leb.h (read_n_bytes, read_direct_string): Move from
	read.c.
