Revert "Allow non-absolute values for bootstrap GHC variable"

This broke configure in subtle ways resulting in #25076 where hadrian
didn't end up the boot compiler it was configured to use.

This reverts commit 209d09f52363b261b900cf042934ae1e81e2caa7.

Fix bad bug in mkSynonymTyCon, re forgetfulness

As #25094 showed, the previous tests for forgetfulness was
plain wrong, when there was a forgetful synonym in the RHS
of a synonym.

Define Eq1, Ord1, Show1 and Read1 instances for basic Generic representation types

This way the Generically1 newtype could be used to derive Eq1 and Ord1
for user types with DerivingVia.

The CLC proposal is https://github.com/haskell/core-libraries-committee/issues/273.

The GHC issue is https://gitlab.haskell.org/ghc/ghc/-/issues/24312.

compiler: Fix emitting a confusing error for non visible class method

Changes the error message when trying to lookup names on GRE that
`must_have_parent` but we get an `AmbiguousOccurrence`. The new
behavior now points the user to the missing name, instead of the
name clash which would be unhelpful in solving their compiling issue.

Fixes #24452

compiler: refactors renamer lookup for sub binder occurences

Refactors lookupSubBndrOcc_helper into two functions that separately
deal with lookup for type classes and export lists. Removes the
Semigroup instance of DisambigInfo in favor of directly filtering
the GRE occurences, the refactored logic also fix and issue with
a program with multiple references being incorrectly accepted

Fix #25014
