Add text-input-v1 support

[dragove]

support text-input-v1 can help to make fcitx5 work in electron apps on native wayland.

support in kde is here: https://invent.kde.org/plasma/kwin/-/merge_requests/3403

chromium patchset for TI3: https://chromium-review.googlesource.com/c/chromium/src/+/3220698

(this is just a ref)

Do you have any other apps that use v1 other than chromium? For some weird reason chromium doesn't wanna send any events even though it binds properly. Maybe it also expects ime v1? tho that would be fucking weird.

@vaxerski Did you pass the parameters that chromium needs?
--enable-features=UseOzonePlatform --ozone-platform=wayland
--enable-wayland-ime --gtk-version=4

[I-Want-ToBelieve]

I found something interesting. Fcitx5 running on hyprland can work in Microsoft’s edge browser.

--gtk-version=4 forces TI3 instead of TI1 that I am implementing.

[vaxerski]

oh. --enable-wayland-ime did it. Thanks.

#1778 btw

[dragove]

I've tested #1778 with this app: https://github.com/Rocket1184/electron-netease-cloud-music and got the same result as q234rty tested. only electron 21 and above version works.
There is a bug that I can't delete my first charater in IME pre-edit region. And I also wonder why the pre-edit region has a yellow background.
btw, It also works on vscode if I use my system electron(22) to launch it. (Though there are some bugs if I don't use electron19 in vscode)

I can't delete the last character a

[vaxerski]

Removing first character fixed in f960f72

regarding the yellow, idk. Should be ZWP_TEXT_INPUT_V1_PREEDIT_STYLE_NONE which should indicate no styling.

I will close this as tiv1 is supported now, feel free to open issues for other bugs.
