Merge of the ConfigureMake and CMakeMake versions of the easyblock for QuantumESPRESSO

[Crivella]

The QuantumESPRESSO ConfigMake and CMakeMake easyblocks have been merged in the same file with a wrapper easyblock deciding which one will get used depending on the version of QE.

This PR would

• replace Archive autotools-based QuantumESPRESSO easyblock and switch default to CMakeMake-based easyblock #3306
• Need changes in fix easyconfigs for recent versions of QuantumESPRESSO easybuild-easyconfigs#20070 to be reverted
• Should be tested with one or more legacy (<=7.3) EC file and with a CMake EC file ({chem} [foss/2023a + intel/2023a] QuantumESPRESSO 7.3.1 with cmake easybuild-easyconfigs#20138)

@boegel I tried merging the 2 easyblocks for QuantumESPRESSO into a new one acting as a wrapper and forwarding the calls to the correct EB based on the version. It is slightly hackish but still very clean code-wise.

Unfortunately eb --list-easyblocks and it's associated unittest is causing the CI to fail, due to having multiple classes defined in one file.
I am not sure if the change i proposed in easybuilders/easybuild-framework#4543 would make sense.

The alternatives would be to either define the classes inside something like another class (or the wrapper class itself) or a dict (anything that will let class not be at the beginning of the string to trick the ^class regex), but that would make the code less maintainable in my opinion.
There is also the option of squashing the classes together and have a wrapper for every ..._step method, but that would make it even less maintainable.

Any suggestion in which direction to proceed?

This is extensively tested in easybuilders/easybuild-easyconfigs#20070 and easybuilders/easybuild-easyconfigs#20138

Put version specific classes inside the wrapper as to not have trouble with framework EB detection regex

This has been extensively tested via easybuilders/easybuild-easyconfigs#20138 and easybuilders/easybuild-easyconfigs#20070 (comment)
