Hadrian now performs substitutions, especially to generate .cabal files
from .cabal.in files. Two benefits:
1. We won't have to re-configure when we modify thing.cabal.in. Hadrian
will take care of this for us.
2. It paves the way to allow the same package to be configured
differently by Hadrian in the same session. This will be useful to
fix #19174: we want to build a stage2 cross-compiler for the host
platform and a stage1 compiler for the cross target platform in the
same Hadrian session.

Previously, when using `capi` calling convention in foreign declarations,
code generator failed to handle const-cualified pointer return types.
This resulted in CC toolchain throwing `-Wincompatible-pointer-types-discards-qualifiers`
warning.
`Foreign.C.Types.ConstPtr` newtype was introduced to handle these cases -
special treatment was put in place to generate appropritetly qualified C
wrapper that no longer triggers the above mentioned warning.
Fixes #22043

This patch fixes pretty-printing of character literals
inside promoted lists and tuples.
When we pretty-print a promoted list or tuple whose first element
starts with a single quote, we want to add a space between the opening
bracket and the element:
'[True] -- ok
'[ 'True] -- ok
'['True] -- not ok
If we don't add the space, we accidentally produce a character
literal '['.
Before this patch, pprSpaceIfPromotedTyCon inspected the type as an AST
and tried to guess if it would be rendered with a single quote. However,
it missed the case when the inner type was itself a character literal:
'[ 'x'] -- ok
'['x'] -- not ok
Instead of adding this particular case, I opted for a more future-proof
solution: check the SDoc directly. This way we can detect if the single
quote is actually there instead of trying to predict it from the AST.
The new function is called spaceIfSingleQuote.
