Move `--ls` behind `-Z ls`

Closes #13549
doc: Removed all definition lists as Sundown doesn't support them.

Closes #13561. Please revert this commit when Sundown (or any
replacement) gets a support for definition lists in the future.
man: Add missing options to rustc.1
rustc: Slightly reword the --no-analysis description for clarity
This is a Windows specific fix in libc. According to MSDN, the GUID
structure's Data2 and Data3 members expect WORD types instead of DWORD. I
discovered this discrepancy while experimenting with some bindings to
Microsoft's OLE2 api. The discrepancy was corrupting the contents of the
string returned by UuidToString after I used known GUIDs to test the
accuracy of the function binding. I didn't add test cases because it would
mean adding a dependency to my rather incomplete binding library. However,
the fix produces expected string values when tested.

Closes #13561. All definition lists have been converted to unordered lists. This is a temporary measure; please revert this when Sundown (or any replacement) gets a support for definition lists in the future.
