CMake: Introduce CMake dependent options and print build summary

[Growl1234]

This PR introduces cmake_dependent_option with intention to make the dependency handling logic clearer from the beginning of CMake logic.

Example:

cmake_dependent_option(EXX_DEV "Enable LibRI developing features" OFF "ENABLE_LIBRI" OFF)

This means EXX_DEV is available only when ENABLE_LIBRI is set to ON, and defaults to OFF; if ENABLE_LIBRI=OFF, the EXX_DEV option will be forced to be off. So if one passes -DENABLE_LIBRI=OFF -DEXX_DEV=ON to CMake (by mistake?), the actual resulting logic will be -DENABLE_LIBRI=OFF -DEXX_DEV=OFF.

cmake_dependent_option(ENABLE_ELPA "Enable ELPA for LCAO" ON "ENABLE_LCAO;ENABLE_MPI" OFF)

This means ENABLE_ELPA is available only when both ENABLE_LCAO and ENABLE_MPI are set to ON.

There is one RFC about how we should detect and show the version of MPI, as existing version detection logic seems invalid.

I currently choose to show the real MPI-standard what an MPI implementation follows, as this is generally available for any MPI implementations through a single ${MPI_CXX_VERSION}. For example:

• MPICH 5.0.1 follows MPI-5.0 standard (therefore MPICH (MPI standard: 5.0))
• OpenMPI 5.0.10 follows MPI-3.1 standard (therefore OpenMPI (MPI standard: 3.1))
• Intel MPI 2021.18 follows MPI-4.1 standard (therefore Intel MPI (MPI standard: 4.1))

However, one concern is that users might not be used to it, so might there be other easier way?

Side note: an inconsistent change is made here: ENLABLE_LIBRI will requrie ENABLE_MPI.

If enable LibRI support without MPI, compilation will report error:

Also, require out-of-source CMake build as in-source is dangerous and might affect the real source code in the build process.
