[nvptx, doc] Update misa and mptx, add march and march-map
Update nvptx documentation:
- Use meaningful terms: "PTX ISA target architecture" and "PTX ISA version".
- Remove invalid claim that "ISA strings must be lower-case".
- Add missing sm_xx entries.
- Fix misa default.
- Add march, copying misa doc.
- Declare misa an march alias.
- Add march-map.
- Fix "for given the specified" typo.
gcc/ChangeLog:

* doc/invoke.texi (misa, mptx): Update.
(march, march-map): Add.
