GHCi interpreter: Tag constructor closures when possible.

When evaluating PUSH_G try to tag the reference we are pushing if it's a
constructor. This is potentially helpful for performance and required to
fix #24870.

Implement Data.List.compareLength and Data.List.NonEmpty.compareLength

`compareLength xs n` is a safer and faster alternative to `compare (length xs) n`.
The latter would force and traverse the entire spine (potentially diverging),
while the former traverses as few elements as possible.

The implementation is carefully designed to maintain as much laziness as possible.

As per https://github.com/haskell/core-libraries-committee/issues/257

Unicode: adding compact version of GeneralCategory (resolves #24789)

The following features are applied:
1. Lookup code like Cmm-switches (draft implementation proposed by Sylvain Henry @hsyl20)
2. Nested ifs (logarithmic search vs linear search) (the idea proposed by Sylvain Henry @hsyl20)

-------------------------
Metric Decrease:
    size_hello_artifact
    size_hello_unicode

haddock: Restructure import statements

This commit removes idiosyncrasies that have accumulated with the years
in how import statements were laid out, and defines clear but simple
guidelines in the CONTRIBUTING.md file.

Rename test for #24725

I must have fumbled my tabs when I copy/pasted the issue number in
8c87d4e1136ae6d28e92b8af31d78ed66224ee16.
