Move Plugins into HscEnv (#17957)

Loaded plugins have nothing to do in DynFlags so this patch moves them
into HscEnv (session state).

"DynFlags plugins" become "Driver plugins" to still be able to register
static plugins.

Bump haddock submodule

Don't initialize plugins in the Core2Core pipeline

Some plugins can be added via TH (cf addCorePlugin). Initialize them in
the driver instead of in the Core2Core pipeline.

Add regression test for #10504

This issue was fixed at some point between GHC 8.0 and 8.2. Let's add a
regression test to ensure that it stays fixed.

Fixes #10504.

dwarf: Apply info table offset consistently

Previously we failed to apply the info table offset to the aranges and
DIEs, meaning that we often failed to unwind in gdb. For some reason
this only seemed to manifest in the RTS's Cmm closures. Nevertheless,
now we can unwind completely up to `main`

hadrian: Dump STG when ticky is enabled

This changes the "ticky" modifier to enable dumping of final STG as this
is generally needed to make sense of the ticky profiles.

hadrian: Add a viaLlvmBackend modifier

Note that this also slightly changes the semantics of these flavours as
we only use LLVM for >= stage1 builds.

Drop the profiled, LLVM, and ThreadSanitizer flavour definitions as
these can now be realized with flavour transformers.
