This PR changes how LLVM is built. Consider updating src/bootstrap/download-ci-llvm-stamp. |

I'm not 100% sure if bumping |
|
I don't believe there are pre-built Arm64EC LLVM artifacts, so moot point. |

[win][arm64ec] Add `/machine:arm64ec` when linking LLVM as Arm64EC When the MSVC linker sees an Arm64EC object file, it needs to know if it's linking the final executable as Arm64EC or Arm64X. This change adds the `/machine:arm64ec` flag to the linker when building LLVM as Arm64EC to avoid that ambiguity (and resulting linker error).
