[llvm] [BOLT] Enable standalone build (PR #87196)

https://github.com/pca006132 created https://github.com/llvm/llvm-project/pull/87196
Upstream changes from https://github.com/NixOS/nixpkgs/pull/289587, this enables standalone build for BOLT, which makes packaging easier. Most of the changes in `bolt/CMakeLists.txt` are copied from `clang/CMakeLists.txt`. `bolt/lib/Target/*/CMakeLists.txt` is also modified to compile tablegen instead of relying on files in `LLVM_BINARY_DIR`. `bolt/lib/Utils/CMakeLists.txt` is changed to generate the VCS information by itself instead of relying on `llvm_vcsrevision_h`, which is not available for the standalone build. These changes should not affect existing builds, but will enable standalone build.
`llvm/lib/Target/RISCV/MCTargetDesc/RISCVMCTargetDesc.h` is changed to remove an (apparently) unused `config.h` include which prevents the standalone build from working, so far I don't encounter any compilation issue after removing that config header.
