Hotfix/sangshuduo/td 5136 taosdemo rework for master (#7939)

* cherry pick from develop branch.

* [TD-5136]<feature>: taosdemo simulate real senario.

* update test case according to taosdemo change

* adjust range of semi-random data.

* make demo mode use different tag name and value.

* change malloc to calloc for pid allocation.

* fix typo.

* fix binary length default value and group id logic.

* fix help msg.

* fix aggregation func test.

* minor typo fix.
