Should also link as component.

I'd add this to LLVM_LINK_COMPONENTS above to avoid mixing two styles.

Ah, sure, missed that

Yes, I checked that compiling with the same CMake settings as the dylib build linked all fine. |

Thanks for the approve, can you also merge this please? I don't have the permissions to do that. |

This is a second PR on this patch (first #155572), that fixes the linking problem for
flang-aarch64-dylibtest.The SupportLSP library was made a component library.
This PR moves the generic Language Server Protocol (LSP) server support code that was copied from clangd into MLIR, into the LLVM tree so it can be reused by multiple subprojects.
Centralizing the generic LSP support in LLVM lowers the barrier to building new LSP servers across the LLVM ecosystem and avoids each subproject maintaining its own copy.
The code originated in clangd and was copied into MLIR for its LSP server. MLIR had this code seperate to be reused by all of their LSP server. This PR relocates the MLIR copy into LLVM as a shared component into LLVM/Support. If this is not a suitable place, please suggest a better one.
A follow up to this move could be deduplication with the original clangd implementation and converge on a single shared LSP support library used by clangd, MLIR, and future servers.
What changes
and their namespace was changed from mlir to llvm
I ran clang-tidy --fix and clang-format on the whole moved files (last two commits), as they are basically new files and should hold up to the code style used by LLVM.
MLIR LSP servers where updated to include these files from their new location and account for the namespace change.
This PR is made as part of the LLVM IR LSP project (RFC)
