Add IFPEN test workflow for C++20

[grospelliergilles]

Add C++20 build and test workflow for the following containers:

• ubuntu 2204 gimkl 2021
• ubuntu 2204 foss 2021
• rhel9 foss 2021
• rhel8 foss 2021
• rhel9 gimkl 2021
• rhel8 gimkl 2021

For foss containers, disable the following failing tests:

The following tests FAILED:
	1224 - alien.gtest.CompositeSpace (Failed)
	1225 - alien.gtest.CompositeSpace.mpi-2 (Failed)
	1254 - alien.refmvhandlers.scalar.RedistributorAlgebra.pair.dok.mpi-4 (Timeout)
	1260 - alien.refmvhandlers.scalar.RedistributorAlgebra.pair.csr.mpi-4 (Timeout)
	1266 - alien.refmvhandlers.scalar.RedistributorAlgebra.unique.dok.mpi-4 (Timeout)
	1272 - alien.refmvhandlers.scalar.RedistributorAlgebra.unique.csr.mpi-4 (Timeout)

For gimkl containers, disable the following failing tests:

The following tests FAILED:
	321 - parallel2_synchronize_8proc (Failed)
	322 - parallel2_synchronize_v1_8proc (Failed)
	323 - parallel2_synchronize_v2_8proc (Failed)
	324 - parallel2_synchronize_v3_8proc (Failed)
	328 - parallel2_synchronize_v5_8proc (Failed)
	529 - hydro5_perf_trace (Failed)
	530 - hydro5_perf_trace_4proc (Failed)
	531 - hydrosimd5_trace (Failed)
	532 - hydrosimd5_trace_4proc (Failed)
	637 - loadbalance_test1_12proc (Failed)
	644 - loadbalance_metis1_rep3_12proc (Failed)
	723 - aleph_multi_6proc (Timeout)
	797 - material3_opt7_trace (Failed)
	1228 - alien.gtest.CompositeSpace (Failed)
	1229 - alien.gtest.CompositeSpace.mpi-2 (Failed)

These tests may pass with a more recent version of Intel MPI (current in containers in 2021.4).
