dev-util/mingw64-runtime: add 10.0.0

This version fixes building with vanilla binutils-2.38 wrt
bug #838157, and the (now keyworded) >=binutils-2.38-r2 backport
also fixed it for all versions.

Includes some ebuild cleanups/changes:
- EAPI7->8
- drop unused autotools inherit
- update HOMEPAGE to https non-sourceforge link
- update LICENSE, main license is ZPL + others, and
  tools are GPL-3+ (could probably still use revision)
- remove obsolete rdtsc patch (was bug #786549), been fixed since
  9.0.0 but the fix is different and was letting our patch apply
- namespace is_crosscompile() to avoid confusing pkgcheck,
  note that this is toolchain.eclass' version which is
  different than tc-is-cross-compiler
- inline just_headers/alt_prefix/crt_with(), left crt's
  use_with and use_enable alone given it's less jarring
  and may have additional uses in the future
- move src_configure-only functions inside src_configure
- use econf with ECONF_SOURCE over direct ${S}/configure
- add missing || die for rm / mkdir / push+popd / cpp+grep
 (for cpp, use a case statement for clarity and no tmp variables)
- drop rm's -f, haven't found a situation where it'd fail
- misc style changes like using arrays for econf

Not touching CHOST/CATEGORY/symlinks and friends given haven't
fully reviewed implications for this package + crossdev.
