Add current pkg info to generated `cabal_macros.h` file

Add the version string macro for the package currently being built
to the generated `dist/build/autogen/cabal_macros.h` file. Perviously
this file only contained the version strings of all the dependent
packages, but not the version string of the package itself.

Add the gen-bounds command.

Two kinds of round-trip test:
 * type conversion ProjectConfig -> LegcyProjectConfig and back
 * ProjectConfig -> print -> parse
The latter goes out to the config file format and back.

These tests uncovered a number of issues in our general config code.

We want to reuse the FlagAssignment printer/parser for the config files.

One for testing if globs are trivial, as in they're constant strings
without the possibility of matching more than one thing. This can help
with making better error messages.

Another util for matching file globs in the rebuild monad, and
automatically monitoring the glob.

Getters and setters really need to match up.

Detected by parse/print round trip QC tests.

(cherry picked from commit a82af445)

This defines the new cabal.project files and introduces the notion of a
project root (and the logic for finding it). Also has support for
implicit projects when no cabal.project file is defined.

Supports both reading and writing project files or fragments. The
printing & parsing round trips correctly. QC tests to follow.

This is a key part of the new nix-local-build branch approach, based
around projects with clear configuration state held in a project file
(or extra files).

This has support for file and dirs as packages within a project,
including by glob. It supports both globs that much match a target, and
optional globs that are allowed to match nothing. It has partial support
for local tarball, remote http tarball and remote source repo packages.

This describes in one place the layout of the new dist dir, as used by
the nix-local-build branch. Also a similar approach to describing the
layout of the user-wide cabal directory.

The idea is that this centralises the description and makes it easier
to change and handle systematically (e.g. we have problems currently
with some user-wide files not being reolocatable).

The existing approach has been to parse top level fields and then
separately parse each top level section, and similarly for pretty
printing. A better approach is to follow the pattern for fields and have
a section description. Then we just parse or print fields+sections in
one call. And as a bonus, secitons can have subsections (and could even
do so recursively).

This patch just adds the new functionality. No existing config parsing
is switched over.

withRepoContext keeps its current type (using GlobalFlags). Added
withRepoContext' that takes all the args seprately. Better name
suggestions welcome.

Fix ConfigStateFileErrorMessages

The error messages associated with ConfigStateFileError have been
reformatted and reworded for clarity.

Fixes #3157. The wrapText helper is used to format all error
messages. Previously, it was only used to format IOException errors;
other exceptions would be formatted incorrectly.

Exporting the default rendering style allows us to consistently format
text without needing to write a Text instance.

Fixes #3214.

update -prof Check message

The flag enable-executable-profiling warns to change it to just enable-profiling. So we'll fix that here too so we don't send people down an old path.

Introduce UnresolvedSourcePackage alias

The alias is a shorthand for 'SourcePackage UnresolvedPkgLoc' which is
used all over the place.
