Enable TCO flag filtering on challenge listings

[jmgasper]

REF. https://topcoder.atlassian.net/browse/PROD-2283

Describe the bug
Currently, there is no ability for user to sort or filter challenges that are TCO eligible.

Expected behavior
After the fix, we will have a new TCO Eligible Challenges switch, similar to Recommended Challenges in the FiltersPanel component. Note that the TCO Eligible Challenges switch displays in different states (All challenges, Past Challenges, Open for registration)

<SwitchWithLabel

Tooltip

NOTE The tooltip is in scope as well.

The tool tip text Learn more about TCO should link to https://www.topcoder.com/community/member-programs/topcoder-open

API

We recently added a tco=true flag that can be applied to the challenge API query, like:

https://api.topcoder-dev.com/v5/challenges?tco=true

if tco=true is set, then the API will only return challenges that are part of a TCO (past and current TCOs)
