Merge #4946 #4993 #4998 #4999

4946: Better forced viewport handling r=def- a=Jupeyy For #4939 For the performance warnings refering `vkCmdClearAttachments` ignore them, because this function is only called when: - clear color is changed(open/close editor, switch between entities) to directly flush a clear with the new color - ~~a viewport is used that is "worse" than 5:4 (I don't really want to switch to non renderpass clear completly, since it *can* improve performance -- https://community.arm.com/arm-community-blogs/b/graphics-gaming-and-vr-blog/posts/vulkan-samples "Therefore, avoid using LOAD_OP_LOAD and vkCmdClearAttachments and use LOAD_OP_CLEAR or LOAD_OP_DONT_CARE whenever possible.")~~ thinking about it, maybe i can also drop this call now, since its dynamic viewport anyway ## Checklist - [x] Tested the change ingame - [ ] Provided screenshots if it is a visual change - [ ] Tested in combination with possibly related configuration options - [ ] Written a unit test if it works standalone, system.c especially - [ ] Considered possible null pointers and out of bounds array indexing - [ ] Changed no physics that affect existing maps - [ ] Tested the change with [ASan+UBSan or valgrind's memcheck](https://github.com/ddnet/ddnet/#using-addresssanitizer--undefinedbehavioursanitizer-or-valgrinds-memcheck) (optional) 4993: Unselect text after ctrl-u r=Jupeyy a=def-  ## Checklist - [x] Tested the change ingame - [ ] Provided screenshots if it is a visual change - [ ] Tested in combination with possibly related configuration options - [ ] Written a unit test if it works standalone, system.c especially - [ ] Considered possible null pointers and out of bounds array indexing - [ ] Changed no physics that affect existing maps - [ ] Tested the change with [ASan+UBSan or valgrind's memcheck](https://github.com/ddnet/ddnet/#using-addresssanitizer--undefinedbehavioursanitizer-or-valgrinds-memcheck) (optional) 4998: Refactor tooltips and add some more r=def- a=edg-l Refactored tooltips so they render last, otherwise stuff rendered after the call is overlapped.
