  [clang][CIR][doc] Add auto-generated ClangIR documentation (#190354)

ClangIR has a collection of documentation pages that we want to upstream
as part of the main clang documentation. These pages are originally
available at https://clangir.org/, maintained in the [incubator
repository](https://github.com/llvm/clangir) which has been archived a
few months ago.

This patch makes a first step towards the upstreaming of ClangIR
documentation. The pages included in this patch are those automatically
generated from MLIR TableGen. Specifically, this patch makes the
following changes to the main clang documentation tree:

- It adds a new subdirectory `CIR` under `clang/docs` to hold all
ClangIR documentation. There are already 3 ClangIR design documents put
under `clang/docs`, and this patch moves all of them to this new
subdirectory.
  - It touches the necessary CMake files and Python scripts to:
- Generate ClangIR language reference automatically from MLIR TableGen
when building the clang documentation with `CLANG_ENABLE_CIR=ON`.
- Incorporate these automatically generated documents (if any) into the
main clang documentation build tree.
