[Bazel] Migrate to bzlmod for LLVM compatibility (#22771)

LLVM has fully migrated to bzlmod and now requires bzlmod features. This
change migrates IREE's Bazel build to use bzlmod.

Changes:
- Add MODULE.bazel with dependencies matching LLVM's versions
- Add build_tools/bazel/extensions.bzl module extension for creating
IREE-specific repositories
- Enable bzlmod in iree.bazelrc
- Update flatcc BUILD.overlay to use includes= instead of hardcoded
-Iexternal/... paths (bzlmod changes external paths)
- Update bitcode library paths for bzlmod repository naming
- Update llvm-project submodule to include upstream bzlmod changes
- Add BZLMOD_LLVM.md documentation for downstream consumers

The iree_extension creates llvm-raw only when IREE is the root module,
allowing downstream consumers to provide their own LLVM by creating
their own llvm-raw repository.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.
