fix: Wayland general CSD fixes (#35206)

Browse Source 
* fix: broken wayland window decorations due to botched chromium update

The `GetTitlebarBounds().height()` is obviously intended to be placed in
the `top` parameter, which used to be the second one before upstream
removed multi-parameter `gfx::Rect::Inset`, but it's the first parameter
for `gfx::Insets::TLBR`, which was intended to replace the removed
`Inset` function. However, whoever updated Chromium kept the parameter
unchanged, causing the title bar height to be passed to the `left`
parameter, causing the window title bar to be unclickable.

* fix: wayland window top bar buttons unclickable

Use NonClientFrameView::TargetForRect for the ClientFrameViewLinux
implementation because the default inherited from FramelessView blocks
any non-HTCLIENT events.

* fix: add maximized parameter to LinuxUI::GetWindowFrameProvider

* fix: pass frame_->IsMaximized() to GetWindowFrameProvider

This ensures that the toolkit renders the window decorations in maximized mode
while the window is maximized to ensure that there is no empty space around the window.

Subject: Add maximized parameter to LinuxUI::GetWindowFrameProvider
This allows ClientFrameViewLinux to instruct the toolkit to draw the window
decorations in maximized mode where needed, preventing empty space caused
by decoration shadows and rounded titlebars around the window while maximized.
