Tested x86_64-pc-linux-gnu, applying to trunk.

coroutines.exp was basically only there to add -std=c++20 to all the tests;
removing it lets us use the general support for running tests under multiple
standards. Doing this revealed that some tests that specifically run in
C++17 mode were relying on -std=c++20 followed by -std=c++17 leaving
flag_coroutines set, which seems unintentional, and different from how we
handle other feature flags. So this changes that, and adds the missing
-fcoroutines to those tests.
gcc/testsuite/ChangeLog:
* g++.dg/coroutines/co-await-syntax-09-convert.C: Add -fcoroutines.
* g++.dg/coroutines/co-await-syntax-10.C
* g++.dg/coroutines/co-await-syntax-11.C
* g++.dg/coroutines/co-await-void_type.C
* g++.dg/coroutines/co-return-warning-1.C
* g++.dg/coroutines/ramp-return-a.C
* g++.dg/coroutines/ramp-return-c.C: Likewise.
* g++.dg/coroutines/coroutines.exp: Removed.
* lib/g++-dg.exp: Start at C++20 for coroutines/
gcc/c-family/ChangeLog:
* c-opts.cc (c_common_post_options): Set flag_coroutines.
(set_std_cxx20, set_std_cxx23, set_std_cxx26): Not here.
