Remove redundant typedefs

I was inspired by this patch of Simon's:

https://sourceware.org/pipermail/gdb-patches/2020-November/173522.html

... to remove other typedefs that are no longer necessary now that gdb
uses C++.

I didn't remove absolutely every one -- I didn't touch the tdep files.
However, I removed many of them.  In some cases, I removed an existing
different struct tag.
