Mohammad Amin Mollazadeh cc16769179 [SHELL32] Fix focus glitch when hovering separators with submenu open (#7932) ...

CORE-20124

Since `TB_HITTEST` returns negative numbers for ID for separator menu items [^1],
shell menu assumes mouse moved outside of the menu popup, highlighting the menu
item for currently open submenu.
To fix this behavior, we can detect separators in `CMenuFocusManager::ProcessMouseMove`
and negate the ID returned by `TB_HITTEST` to make it a positive number again,
so the shell menu wouldn't glitch.
