    [feat](FE) add rest api to get last profile (#38268)
    
    ## Proposed changes
    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
    
    Issue Number: close #xxx
