Build functioning dev packages for IREECompiler and IREERuntime. (#16008)
With this patch, external projects can do:
```
find_package(IREECompiler)
find_package(IREERuntime)
```
and access our targets by adding either the build or install tree
`lib/cmake/IREE` to the CMake package search path.
There are still some ergonomic issues that need to be addressed going
forward:
* cpuinfo breaks the one downstream I am testing this against. We really
should just finish killing that, so I am setting
-DIREE_ENABLE_CPUINFO=OFF in the dist package.
* We are not yet re-establishing the pretty `iree::runtime:...` aliases.
The underscore versions are available (`iree_runtime_...`).
* I want to further isolate the remaining bundled deps (yaml and
flatcc).
* New convenience install targets do not have full dependency
information. Need to do an `all` build first.
As part of this, I did some longstanding cleanups:
* Normalized the install component namespace. Defined
`IREECMakeExports`, `IREEDevLibraries-Compiler`,
`IREEDevLibraries-Runtime`, `IREERuntimeLibraries-Compiler`,
`IREEBundledLibraries`, `IREETools-Runtime`.
* Added convenience `iree-install-*` targets. Each includes a
`-stripped` variant as well.
* Moved MLIRInterop.h to the bindings/c directory where it should have
been all along and straightened the deps.
* Install the mlir-c headers to support libIREECompiler.so dev.
* Added the "busybox" tool binaries to the install distribution
(iree-lld, etc).
* Stopped bundling upstream `lld` and `clang` by default because they
bloat the size. `lld` is now bundled as `iree-lld` just like in the
Python packages. Clang and llvm-link can be gotten by installing the new
`IREETools-CompilerExtra` component if folks need those.
Note that this only installs public headers and libraries needed to
build against the compiler and runtime. Installing private things needed
to develop parts of the system are out of scope.
