Add IREE_COMPILER_BUILD_SHARED_LIBS option. (#12310)

* Balances all of the angels on the head of the pin such that when using
it, trivial changes to the compiler that would usually require a lengthy
re-link happen in <1s.
* Fixes some indirect dependencies that were missing (and enforced with
stricter linking).
* This is the equivalent of how LLVM interprets -DBUILD_SHARED_LIBS=ON,
scoped to just IREE's bundled LLVM, LLVM sub-projects and compiler
sources.
* As with all uses of BUILD_SHARED_LIBS, the support matrix for this
feature is sparse: there are many ways it will not work outside of its
strict case for supporting development.
* iree-run-module is not happy (complaining of duplicate option
registration). Will triage separately.
* This probably only works on Linux right now. It likely can work on
MacOS, but the libIREECompiler.dylib will need to be rigged with
--reexport_library (which is effectively the default for dynamically
loaded ELF). I don't think this will work on Windows without substantial
work.
* I am intending to use this mode to enable rapid reload of dynamically
built plugins, etc.
