map-layer v6 release todos

[hl662]

Following the merge of this PR, ~we still have some usage of deprecated appui APIs that would take a more focused effort to remove.~. Removed deprecated via this PR. Once we address sub-issue attached, we can reliably move map-layers to v6.0.0.

Here are the list of things left:

Tasks

• [x] Replace usage of ImageCheckbox in SubLayersTree component.
• [x] Replace ResizableContainerObserver, either by dropping it entirely or resorting to third party libraries.
• [x] Address replacing NumberSelect with iTwinUI Select, with more custom handling to fit previous NumberSelect functionality
• [x] Replace usage of core-react Popup with iTwinUI Popover. Adjacent matter, useOnOutsideClick is deprecated, custom handling of outside clicks for these components have to be added
• [x] replace all deprecated code
• [x] The map manager settings popover has some inside elements going outside the bounds of the popover, make sure the parent element wraps the other one
• [x] https://github.com/iTwin/viewer-components-react/issues/1188

Issues with popups that need to be resolved:

• transparency slider

• add layer popup for backgrounds and overlays

• attach map layer for backgrounds and overlays

I think moving to iTwinUI completely should help resolve this, need to remove all usage from itwin/core-react

Few bugs:

• The edit custom layer / add new custom layer modal only lets you type in one character at a time, with the input field unfocusing after every type.
• Same issue above with the add custom query parameter modal.
• The sublayer popover could have the search bar shifted a bit to the right more

• The map manager settings popover has some inside elements going outside the bounds of the popover, we want to make sure the parent element wraps the other one
