Make template-haskell a stage1 package

Promoting template-haskell from a stage0 to a stage1 package means that
we can much more easily refactor template-haskell.

We implement this by duplicating the in-tree `template-haskell`.
A new `template-haskell-next` library is autogenerated to mirror `template-haskell`
`stage1:ghc` to depend on the new interface of the library including the
`Binary` instances without adding an explicit dependency on `template-haskell`.

This is controlled by the `bootstrap-th` cabal flag

When building `template-haskell` modules as part of this vendoring we do
not have access to quote syntax, so we cannot use variable quote
notation (`'Just`). So we either replace these with hand-written `Name`s
or hide the code behind CPP.

We can remove the `th_hack` from hadrian, which was required when
building stage0 packages using the in-tree `template-haskell` library.

For more details see Note [Bootstrapping Template Haskell].

Resolves #23536

rts: Ignore EINTR while polling in timerfd itimer implementation

While the RTS does attempt to mask signals, it may be that a foreign
library unmasks them. This previously caused benign warnings which we
now ignore.

See #24610.

EPA: Add additional comments field to AnnsModule

This is used in exact printing to store comments coming after the
`where` keyword but before any comments allocated to imports or decls.

It is used in ghc-exactprint, see
