Move useChannels & SearchChips to kolibri-common

[nucleogenesis]

Summary

• Moves SearchChips into kolibri-common w/ other Search components
• SearchChips gets languages from injectBaseSearch#availableLanguages instead of useLanguages
• Moves useChannels (and mocks) into kolibri-common - this simplified the SearchChips move as it depends on useChannels and useChannels seems well suited for a move to the common package
• Removes useLanguageses and all references to it
• Updates references throughout

References

Closes #12720

Reviewer guidance

• Can you search and navigate the Library without issue?
• Can remove search chips by clicking their X (or by clicking "clear all")
• Languages work in the search filters (this was the bug that led me to find this issue)

Something is still iffy (check the console errors) when filtering by languages, as no selected language search chips appear when tested the EXE asset from this PR in Firefox. This was working correctly in 0.17.1:

Ah yes, this is confirmed by @radinamatic's testing - this needs to either get the availableLanguages or access the .value.

[nucleogenesis]

@radinamatic sorry for the delay here - I've fixed the issue noted and the language chips show up correctly now.

[rtibbles]

Not seeing any code concerns in here, all useful cleanup.

[pcenov]

LGTM now @radinamatic - the issue reported by you is fixed now and there are no regressions caused by this PR.

[rtibbles]

Code checks out, QA checks out. This is good to merge.

Thank you @pcenov! 👍🏽

@nucleogenesis I did notice one thing while testing over the weekend, and I wanted to investigate more but then the ⛈️ happened: Clear all button does clear the displayed search results and the filter applied for the search actions performed using Keywords, Categories, Activities and the Show resources options.

However, it does not clear the applied filters for any of the dropdown options (Language, Level, Channel, Accessibility). Search results are cleared, but the previously applied filter apparently stays visible, but not actually applied anymore, and the user needs to clear them manually. This can be confusing and we should force them cleared as for the other filtering options in the sidebar.
