[VL] Simplify JniLibLoader

[zhztheplayer]

Description

Overtime we find that JniLibLoader might be over-designed. Given that when a shared library is unable to be loaded, Gluten usually just refuses to do anything (e.g., just crashes). Thus ideally we load all the libraries needed, or we just raise fatal error.

JniLoader implemented a transactional loading mechanism that supports loading all the specified libraries together and with a rarely used "roll back" API. These stuffs may be the first priority to remove in the topic to simplify code.

Hi @zhztheplayer I would like to work on this. Can you give some more clarity, we want to get rid of the transactional loading?

we want to get rid of the transactional loading?

I think it doesn't make any actual difference with loading the libs one by one. Probably we can test and prove. The issue is somewhat benign as nevertheless we don't have much code in JniLibLoader.java. Anyway, feel free to take if you want. Thanks.

I see thanks! I can do some testing and raise changes
