Add linux.riscv64 environment to eclipse-platform-parent and publish linux.riscv64 artifacts

[HannesWell]

Similiarly like it was done for Windows on ARM:

• Add win32.aarch64 environment to eclipse-platform-parent and publish win32.aarch64 artifacts #1917
• [I-Build] Copy built products for Windows on Arm to publication area #2017

Part of #2310.

@yuzibo FYI

@merks we also need something similar to #1953.
But when I add a <configurations operatingSystem="linux" windowSystem="gtk" architecture="riscv64"/> the Aggregator Editor cannot open the file anymore.
I'll therefore hold that off until we have support for riscv64 architectures. Can you tell if this has to be added explicitly or is this inherited at some point in time?

Thank you. I will add this to the summary list also.

I change to the *.aggr made the job fail:

#2397

The validation fails:

How long do we think we'll be in this state where there a requirements that can't be satisfied? If that's a while, then I should revert that commit to the SDK4Mvn.aggr...

I hope it isn't long.
In general I believe we have the most difficult parts in place and just have to plugin in the missing pieces. I assume this to be a big one, but I first have to investigate why this is failing.

[HannesWell]

I have now investigated the failure in detail and found out that in the end the p2-baseline replacement removed the linux.riscv64 root-files in the o.e.equinox.executable.feature.
I have created eclipse-equinox/equinox#680 to fix that and explained it in detail there.
@yuzibo I have added the latter to #2310.

Temporarily I have changed the .gitmodules to build with eclipse-equinox/equinox#680 before it is submitted.

[HannesWell]

Testing was successful and this PR is now in it's final state.
After the build has succeeded, I'll submit this and want to start a new I-build immediately to verify everything works as expected.

Just started https://ci.eclipse.org/releng/job/Builds/job/I-build-4.34/50/.

[yuzibo]

Thanks!

[HannesWell]

Just started https://ci.eclipse.org/releng/job/Builds/job/I-build-4.34/50/.

This build succeeded and the org.eclipse.equinox.launcher.gtk.linux.riscv64 and org.eclipse.swt.gtk.linux.riscv64 fragments are now available in the corresponding I-build repository.
The new download links also all work as expected.

Thanks!

You're welcome. And thanks for all your contributions.
