Unify compiler and runtime HAL driver plugin systems. (#15551)

Functional changes:

* CMake variable -DIREE_COMPILER_PLUGIN_PATHS is now generically
-DIREE_CMAKE_PLUGIN_PATHS.
* Super-project variable IREE_COMPILER_BUILTIN_PLUGIN_PATHS is similarly
renamed.
* Plugin directories can contain an iree_compiler_plugin.cmake (changed
from iree_compiler_plugin_group.cmake) file and/or
iree_runtime_plugin.cmake file.
* External HAL drivers are not configured with loose CMake variables
anymore (since they do not span scopes correctly): they use GLOBAL
properties of the same name.
* We recommend using the iree_register_external_hal_driver() function to
setup HAL driver registration vs setting loose properties. In-tree
drivers are switched to this.

This was tested on a private branch of the iree-amd-aie repo, which will
require some post-submit adjustment.

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.

Project Status

IREE is still in its early phase. We have settled down on the overarching infrastructure and are actively improving various software components as well as project logistics. It is still quite far from ready for everyday use and is made available without any support at the moment. With that said, we welcome any kind of feedback on any communication channels!

  • MLIR topic within LLVM Discourse: IREE is enabled by and heavily relies on MLIR. IREE sometimes is referred to in certain MLIR discussions. Useful if you are also interested in MLIR evolution.
