[Lldb-commits] [lldb] Make the target's SectionLoadList private. (PR #113278)

https://github.com/clayborg created https://github.com/llvm/llvm-project/pull/113278

Lots of code around LLDB was directly accessing the target's section load list. This NFC patch makes the section load list private to the Target class can access it, but everyone else now uses accessor functions. This allows us to control the resolving of addresses and will allow for functionality in LLDB which can lazily resolve addresses in JIT plug-ins with a future patch.
