configitems: declare items in a TOML file

Mercurial ships with Rust code that also needs to read from the config.
Having a way of presenting `configitems` to both Python and Rust is needed
to prevent duplication, drift, and have the appropriate devel warnings.

Abstracting away from Python means choosing a config format. No single format
is perfect, and I have yet to come across a developer that doesn't hate all of
them in some way.
Since we have a strict no-dependencies policy for Mercurial, we either need
to use whatever comes with Python, vendor a library, or implement a custom
format ourselves.

Python stdlib means using JSON, which doesn't support comments and isn't great
for humans, or `configparser` which is an obscure, untyped format that nobody
uses and doesn't have a commonplace Rust parser.
Implementing a custom format is error-prone, tedious and subject to the
same issues as picking an existing format.

Vendoring opens us to the vast array of common config formats. The ones
being picked for most modern software are YAML and TOML. YAML is older and
common in the Python community, but TOML is much simpler and less error-prone.
I would much rather be responsible for the <1000 lines of `tomli`, on top of
TOML being the choice of the Rust community, with robust crates for reading it.

The structure of `configitems.toml` is explained inline.

# configitems.toml - centralized declaration of configuration options
#
# This file contains declarations of the core Mercurial configuration options.
#
# # Structure
#
# items: array of config items
# templates: mapping of template name to template declaration
# template-applications: array of template applications
#
# # Elements
#
# ## Item
#
# Declares a core Mercurial option.
#
# - section: string (required)
# - name: string (required)
# - default-type: boolean, changes how `default` is read
# - default: any
# - generic: boolean
# - priority: integer, only if `generic` is true
# - alias: list of 2-tuples of strings
# - experimental: boolean
# - documentation: string
#
# ## Template
#
# Declares a group of options to be re-used for multiple sections.
#
# - all the same fields as `Item`, except `section` and `name`
# - `suffix` (string, required)
#
# ## Template applications
#
# Uses a `Template` to instanciate its options in a given section.
#
# - template: string (required, must match a `Template` name)
# - section: string (required)
