[llvm] [ORC] Add visibility macros to functions needed by lli and jitlink (PR #113271)

[Thomas Fransham via llvm-commits]

https://github.com/fsfod created https://github.com/llvm/llvm-project/pull/113271

Annotating these symbols will fix missing symbols errors for lli and llvm-jitlink when when the LLVM is built as shared library on windows with explicit symbol visibility macros enabled.

This is part of the work to enable LLVM_BUILD_LLVM_DYLIB and plugins on window.

Annotating these symbols will fix missing symbols errors for lli and llvm-jitlink when
when the LLVM is built as shared library on windows with explicit symbol visibility
macros enabled.
