Improve SoList hiding

[JingMatrix]

Changes

1. Export CMAKE symbols for clangd language server so that current project is more friendly for non-IDE users.
2. Fix linker symbol lookup on Android 15 for some devices ([BUG]: Symbol resolution for /linker in Android 15 #63 )
3. Drop module SoInfo from SoList to avoid detection

Why

In Bionic linker, the SoInfo structure has a field next, which points to the next loaded library in a linked list consisting of all loaded libraries.
Hence, a hooked app can easily find all loaded libraries.
Previously in ReZygisk, module library items are hidden by setting the pathname to be empty. This was futile for two reasons:

1. The name field still keeps the library name
2. An item with empty name or pathname is artificial and can be used to detect Zygisk.

By contrast, dropping the item from SoList is a widely used methods in many projects, such as the well-known Riru.
You can search keyword solist_remove_soinfo on GitHub to find them.

Checkmarks

• The modified functions have been tested.
• Used the same indentation as the rest of the project.
• Updated documentation (changelog).

To get a clear idea, this pull-request will log new items like this:

[ 2024-11-29T13:47:30.494    10242: 16356: 16356 I/zygisk-core64   ] Dropped SoList entry for liblspd.so loaded at /memfd:jit-cache-zygisk (deleted)

[JingMatrix]

Very interestingly, we cannot drop the soinfo of libzygisk.so loaded from /data/adb/rezygisk/lib64/libzygisk.so.
Otherwise, zygisk modules will fail to work, a testing commit is JingMatrix@c5ac305

[JingMatrix]

I made an app to detect ReZygisk: JingMatrix/Demo.
Here are the results:

1. No versions of ReZygisk ever passed the second test of solist;
2. Current PR will help to pass the first test of solist

[JingMatrix]

Current pull-request can be merged.

To bypass the test of Demo, here is idea of injecting libzygisk.so to be implemented later :

1. In daemon, remote call dlopen to load libzygisk.so
2. In libzygisk.so, move/copy its memory block to a new place, and return the new address back to daemon
3. In daemon, remote call dlclose to clean all traces introduced by the dynamic linker, including the one of solist
4. In daemon, remote call entry function using the new address returned in step 2

Basically, we now move the memory block of libzygisk.so instead of simply renaming it.
