Although I don't know why Ergo-L keyboard layout behave differently on my
environment and the reporter's environment. In the reporter's environment,
second dead key press causes `WM_DEADCHAR` with `0` `wParam`. Then,
`GetFollowingCharMessage()` returns `false` so that it's not stored into
`mFollowingCharMsgs`. Then, `NativeKey::IsFollowedByDeadCharMessage()` returns
`false` and `NativeKey::mIsDeadKey` is set to `false`. Therefore, `NativeKey`
dispatches only `eKeyDown` event but whose `.key` is `"g"` rather than
`DeadKey` and finally, fails to call `KeyboardLayout::ActivateDeadKeyState()`.
Therefore the following dead key sequence is not treated as so.
This patch makes it return `true` for such `WM_DEADCHAR` message so that the
`WM_KEYDOWN` message will be treated as a dead key sequence.

When a printable key is pressed with `Alt`, Windows notify us of `WM_SYSKEYDOWN`
and `WM_SYSCHAR`. However, if the builtin IME for inputting a Unicode character
consumes some printable key presses, Windows does not notify us of `WM_SYSCHAR`.
Therefore, if `WM_SYSKEYDOWN` comes without `WM_SYSCHAR`, we should consume
the `eKeyDown` before dispatching the event so that the key press won't be
handled by access key of the menu nor the content.

As far as I've tested on Win 11, we can put it off to load it when first needed
of the keyboard layout data. `ToUnicodeEx` API changes the dead key state and
it's called a lot in `KeyboardLayout::LoadLayout`, however, this patch does
not newly call `LoadLayout` after `TranslateMessage` API at least while handling
a key message. Therefore, this should be safe but regressions of this change
could be serious, so this makes it enabled only in early beta and earlier for
now.

A lone surrogate should not appear in `DOMString` at least when the attribute
values of events because of ill-formed UTF-16 string.
`TextEventDispatcher` does not handle surrogate pairs correctly. It should not
split surrogate pairs when it sets `KeyboardEvent.key` value for avoiding the
problem in some DOM API wrappers, e.g., Rust-running-as-wasm.
On the other hand, `.charCode` is an unsigned long attribute and web apps
may use `String.fromCharCode(event.charCode)` to convert the input to string,
and unfortunately, `fromCharCode` does not support Unicode character code
points over `0xFFFF`. Therefore, we may need to keep dispatching 2 `keypress`
events per surrogate pair for the backward compatibility.
Therefore, this patch creates 2 prefs. One is for using single-keypress
event model and double-keypress event model. The other is for the latter,
whether `.key` value never has ill-formed UTF-16 or it's allowed.
If using the single-keypress event model --this is compatible with Safari and
Chrome in non-Windows platforms--, one `keypress` event is dispatched for
typing a surrogate pair. Then, its `.charCode` is over `0xFFFF` which can
work with `String.fromCodePoint()` instead of `String.fromCharCode()` and
`.key` value is set to simply the surrogate pair (i.e., its length is 2).
If using the double-keypress event model and disallowing ill-formed UTF-16
--this is the new default behavior for both avoiding ill-formed UTF-16 string
creation and keeping backward compatibility with not-maintained web apps using
`String.fromCharCode`--, 2 `keypress` events are dispatched. `.charCode` for
first one is the code of the high-surrogate, but `.key` is the surrogate pair.
Then, `.charCode` for second one is the low-surrogate and `.key` is empty
string. In this mode, `TextEditor` and `HTMLEditor` ignores the second
`keypress`. Therefore, web apps can cancel it only with the first `keypress`,
but it indicates the `keypress` introduces a surrogate pair with `.key`
attribute.
Otherwise, if using the double-keypress event model and allowing ill-formed
UTF-16 --this is the traditional our behavior and compatible with Chrome in
Windows--, 2 `keypress` events are dispatched with same `.charCode` values as
the previous mode, but first `.key` is the high-surrogate and the other's is
the low surrogate. Therefore, web apps can cancel either one of them or
both of them.
Finally, this patch makes `TextEditor` and `HTMLEditor` handle text input
with `keypress` events properly. Except in the last mode, `beforeinput` and
`input` events are fired once and their `data` values are the surrogate pair.
On the other hand, in the last mode, 2 sets of `beforeinput` and `input` are
fired and their `.data` values has only the surrogate so that ill-formed
UTF-16 values.
Note that this patch also fixes an issue on Windows. Windows may send a high
surrogate and a low surrogate with 2 sets of `WM_KEYDOWN` and `WM_KEYUP` whose
virtual keycode is `VK_PACKET` (typically, this occurs with `SendInput` API).
For handling this correctly, this patch changes `NativeKey` class to make it
just store the high surrogate for the first `WM_KEYDOWN` and `WM_KEYUP` and use
it when it'll receive another `WM_KEYDOWN` for a low surrogate.

Currently, log names of IME handlers and keyboard event handlers are considered
from the class names. However, some of them are older name, and some of them
are for multiple classes. This is hard to remember when I tell bug reporters
to log the behavior in their environment. Therefore, I'd like to name all
IME handlers' log module name is `IMEHandler`, and all keyboard handlers'
log module name is `KeyboardHandler`.
Without dumping each key mapping on Windows, the log level `4` (`LogLevel::Debug`)
is enough. `KeyboardHandler:5` is really noisy on Windows. So, new logging
preparation becomes:
`MOZ_LOG=IMEHandler:4,sync`
`MOZ_LOG=KeyboardHandler:4,sync`
or
`MOZ_LOG=IMEHandler:4,KeyboardHandler:4,sync`
