fix(native-filters): Don't send unnecessary PUT request on dashboard render

[kgabryje]

SUMMARY

When dashboard first renders, we calculate tabs and charts in scope of each native filter. Before, we used to send a PUT request with the results, which also modified dashboard's metadata. This PR fixes that behaviour by saving the results only in redux, without sending them to the backend. Also, now we run the calculations only if the native filters feature flag is enabled
This PR is related to an issue raised by @graceguo-supercat in comments #14933 (comment) and #14933 (comment). The problem with setting properties show_native_filters and native_filter_configuration was not caused directly by PR #14933, but the problem was elevated by that PR because of sending unnecessary PUT request. The root of the issue will be handled in a separate PR by @villebro.

Thanks for the quick fix! Works like expected, but one minor non-blocking comment regarding naming.
