[feat](FE) add rest api to get last profile (#38268) (#38451)

Browse Source 
## Proposed changes
pick from #38268

if you want to get the profile of the query just executed, it not
neccessary to find the query_id now.
this is useful to get profiles in shell script, for example, we want to
get all profiles of tpcds queries (103 query profile) in a shell script.

before:
curl

http://root:@127.0.0.1:8030/api/profile/text?query_id=990cc3b19e464e03-a3af05a997eb4091
> profile
after:
curl http://root:@127.0.0.1:8030/api/profile/text > profilex
