Summary description: An expandable key=val implementation and friends

Announcement text:
----------------------------------------------------------------------
`expkv-bundle` replaces the earlier CTAN packages `expkv`, `expkv-cs`,
`expkv-def`, and `expkv-opt` to distribute them as a single CTAN-package
(they are still individual LaTeX-packages). There were some changes to
the individual packages that might break backwards compatibility in
edge cases. The most noteworthy change perhaps is the new expansion control
mechanism for key=value input supported by all packages in the bundle.

A complete changelog can be found at
https://gitlab.com/islandoftex/texmf/expkv-bundle/-/blob/master/changelog.md

The following changes might break existing code:

## `expkv`
- allow access to the raw key names in unknown handlers (might break existing
code if `\par` is part of a key name and your unknown handlers aren't
defined `\long`, also might break existing uses of `\ekvletunknown` and
`\ekvletunknownNoVal`, as the macros should now expect an argument more)
- `\ekvsetdef` no longer defines the macro as `\long` automatically (use a
prefix if you need to)
- the expansion control might break existing uses of `\ekvparse` if the keys
contain a colon followed by a space (only if the tokenlist following the
space is not blank and the colon is not preceded by a space)

## `expkv-cs`
- the unknown handlers defined with `...` forward the raw key names now.
- the unknown handlers defined with `...` forward the key name surrounded by one
set of braces and spaces now
- use `\ekvmorekv` for `meta` and `nmeta` instead of a nested `\ekvset` (might
affect behaviour if a set-changing key is used in the meta list, though this
would most likely break in `expkv-cs` in the first place)

## `expkv-def`
- add `unprotected` prefix for choices (might break existing choices starting
with that word)
- use `\expanded` in `estore`, `xstore`, `edata`, `xdata`, `edataT`, `xdataT`,
`einitial`, and `edefault` instead of `\edef` expansion. Might break
existing usage using `#`-doubling.
- use `\ekvmorekv` for `meta` and `nmeta` instead of a nested `\ekvset` (might
affect behaviour if a set-changing key is used in the meta list, you can get
the old behaviour using `smeta` or `snmeta`)
- allow values stored in the underlying control sequence differing from their
choice in `choice-store` (might break existing choices containing an equals
sign)

## `expkv-opt`
- the deprecated `\ekvoProcessUnusedGlobalOptions` now throws an error (will be
removed next version)
- also remove from unused global options if in a class the local options are
identical to the global options and the unused global options aren't empty
