Fixed: Not able to upload 512MB+ custom apps anymore.

[MohitMaliFtechiz]

Fixes #3511

• Introduced the splitting zim file with 500MB for custom apps. Since the bundle has a limit for a file to upload it uses the play asset delivery mode, and for new custom apps, playStore does not allow to upload the apk (with apk we can upload more than 1GB file). So to address this issue we have introduced a feature in libzim where we can load the zim files via the fd list.
• We have modified our code to upload the files with 500MB chunks in the asset folder, and later we are accessing these files from the asset folder and creating the archive object with the help of the new libzim feature.
• Currently CI will fail because we are using the new libzim feature in this PR. But currently new binding of java-libkiwix is not released once the new binding is released and we start using that then this error will resolve.

@MohitMaliFtechiz Thx for rhis PR, but its important to notice that we won't be able to put more than 3 chunks=1.5GB as asset. It does not fully fix the problem AFAIK

[MohitMaliFtechiz]

@kelson42 We have a total combined limit of 1GB for install-time that we are currently using, above this, we still have the problem.
