[llvm] [ORC] Move Mangler implementation from OrcShared to OrcJIT (PR #221942)

[Lang Hames via llvm-commits]

https://github.com/lhames created https://github.com/llvm/llvm-project/pull/221942

Many OrcJIT clients don't directly depend on OrcSupport, and so broke when e91092685eab moved mangling from OrcJIT to OrcSupport.

We want to reorganize these libraries in the not too distant future. Rather than forcing clients to update dependencies that may change again soon, move the code (but not the header) back into the OrcJIT library. We can address the mismatch between the header's and implementation's home during the library reorganization.
