[abseil] Use std:: types when feature cxx17 is enabled (#11039)
Adds a patch changing macros in absl/base/options.h to
always use the std:: namespace types instead of the
absl:: namespace replacements (for any, optional,
string_view, variant).
The upstream version of options.h uses compiler/library
feature detection to decide this, but patch
fix-lnk2019-error.patch hard codes use of absl:: types,
thus rendering setting CMAKE_CXX_STANDARD to 17 in the
port file ineffective. Since auto detection is problematic
from an ABI point of view (see comments in
absl/base/options.h for details), this applies an
alternate patch for fix-lnk2019-error.patch when feature
cxx17 is enabled.
