fix: shorten url with extra request parameters

[graceguo-supercat]

SUMMARY

In #10651 I added a feature that standalone iframe can use shorten url.
But later I found there is issue for the existed solution: we store full url in url tbl, which supposed to be content for form_data parameter only. For standalone chart, its full url is like: form_data={key1:value1, key2: value2}&standalone=true&height=400.

This PR is to fix this issue:

• remove extra parameters standalone and height from shorten url request, request shorten url with only form_data parameter.
• create standalone url from frontend, with shorten url id and attach standalone=true and height parameter. So the shorten url for standalone chart will be like http://localhost:8080/superset/explore/?r=8015&standalone=true&height=600

TEST PLAN

CI and manual test

LGTM. At some point it would be nice to start porting these to TS and do some additional simplification, especially exploreUtils has some very loaded functions.
