[commit] Improve documentation of Windows debugging options

[Eli Zaretskii <eliz at gnu dot org>]

FYI: I found some typos and inaccuracies in the description of the
Windows "set/show debug..." options, so I fixed them as below.

Committed.

	* gdb.texinfo (Cygwin Native): Fix typos.  Clarify the types of
	debugging information produced by the various "set debug..."
	options.
