Add template-haskell-lift and template-haskell-quasiquote as homes for template-haskell's more stable interfaces

template-haskell-lift just exports Lift and compat shims and is compatible with GHC-8.10+. template-haskell-quasiquoter exports the quasiqoute interface.

I've patched all the boot libraries that previously used template-haskell to use these libraries instead. (Of course these patches will need to be submitted upstream)

Boot libraries done:

• bytestring: https://github.com/haskell/bytestring/pull/717
• containers: https://github.com/haskell/containers/pull/1162
• text: https://github.com/haskell/text/pull/661
• time: https://github.com/haskell/time/pull/285
• exceptions: https://github.com/ekmett/exceptions/pull/105
• filepath: https://github.com/haskell/filepath/pull/258
• os-string: https://github.com/haskell/os-string/pull/36

We probably want these two libraries to live outside the GHC tree. I think it would make sense to also split out the template-haskell library at the same time and place all three in a template-haskell repo, either on the GHC gitlab (my preferred option) or github.
