In the past, we were using `Focus.handleHelp()` to see if we're handling a
`help` command, and print the commands supported by the handler. We also used
`strcmp_P` directly to compare (parts of) our input against command supported by
the handler. This approach works, but had multiple major disadvantages: it
duplicated strings between `handleHelp` and the `strcmp_P` calls, and it relied
on fragile substring pointers to save space.
To replace all that, this patch implements a different approach. Help handling
is split between a check (`Focus.inputMatchesHelp()`) and a
reply (`Focus.printHelp()`), the latter of which takes a list of `PSTR()`
strings, rather than one single string. This allows us to reuse the same
strings for comparing against the handler's input.
The new approach no longer uses the fragile substring pointers, nor does it use
`strcmp_P` directly, but goes through a wrapper (`Focus.inputMatchesCommand()`)
instead.
These changes lead to a more readable pattern. While we do use longer strings as
a result, there is less duplication, and the new patterns also require less
code, so we end up with saving space, at least on AVR devices.
The old methods are still available and usable, but they're deprecated.

This is the result of running the `include-what-you-use` wrapper, followed by
the `clang-format` wrapper on the Kaleidoscope codebase. It is now safe to use
both without needed any manual corrections after the fact, but it's still
necessary to run clang-format after IWYU, because the two differ in the way they
indent comments after header files.

This standardizes namespace closing brackets for namespace blocks. Each one is
on its own line, with a comment clearly marking which namespace it closes.
Consecutive lines closing namespace blocks have no whitespace between them, but
there is one blank line before and after a set of namespace block closing lines.
To generate the namespace comments, I used clang-format, with
`FixNamespaceComments: true`. But since clang-format can't exactly duplicate
our astyle formatting, it made lots of other changes, too. To isolate the
namespace comments from the other formatting changes, I first ran clang-format
with `FixNamespaceComments: false`, committed those changes, then ran it again
to generate the namespace comments. Then I stashed the namespace comments,
reset `HEAD` to remove the other changes, applied the stashed namespace
comments, and committed the results (after examining them and making a few minor
adjustments by hand).

This implements a new `FocusSerial` command: `plugins`. The `plugins` command
will reply back with a list of plugins enabled in the firmware. The list is not
exhaustive, only plugins that opt-in to this mechanism will be listed. It is
opt-in, because for a lot of plugins, having them listed isn't useful in a
practical sense.
The goal with this feature is to allow Chrysalis to detect plugins that would
affect what keys it offers, or which additional settings it displays, and do so
in a consistent way. This is why IdleLEDs has an `onNameQuery` handler too, even
though it can be detected otherwise: for consistency.
