This patch disentangles a bit more DynFlags from the native code
generator (CmmToAsm).
In more details:
- add a new NCGConfig datatype in GHC.CmmToAsm.Config which contains the
configuration of a native code generation session
- explicitly pass NCGConfig/Platform arguments when necessary
- as a consequence `sdocWithPlatform` is gone and there are only a few
`sdocWithDynFlags` left
- remove the use of `unsafeGlobalDynFlags` from GHC.CmmToAsm.CFG
- remove `sdocDebugLevel` (now we pass the debug level via NCGConfig)
There are still some places where DynFlags is used, especially because
of pretty-printing (CLabel), because of Cmm helpers (such as
`cmmExprType`) and because of `Outputable` instance for the
instructions. These are left for future refactoring as this patch is
already big.

- Remove unneeded ones
- Use <..> for inter-package.
Besides general clean up, helps distinguish between the RTS we link
against vs the RTS we compile for.

ghc-pkg needs to be aware of platforms so it can figure out which
subdire within the user package db to use. This is admittedly
roundabout, but maybe Cabal could use the same notion of a platform as
GHC to good affect too.

Summary:
I noticed while playing around with
https://github.com/fbsamples/ghc-hotswap/ that the main binary needs to
have a custom main function to set `config.keep_cafs = true` when
initialising the runtime. This is pretty annoying, it means an extra
C file with some cryptic incantations in it, and a `-no-hs-main` flag.
So I've replaced this with a link-time flag to GHC, `-fkeep-cafs` that
does the same thing.
Test Plan:
New unit test that tests for the RTS's GC'd CAFs assertion, and also
the -keep-cafs flag.

Summary:
SysTools and DriverTools have an annoying mutual dependency.
They also each contain pieces of the linker. In order for
changes to be shared between the library and the exe linking
code this dependency needs to be broken in order to avoid
using hs-boot files.
