taosMemoryFree is declared in taos.h and not exported in windows port

[freemine]

Is your feature request related to a problem? Please describe.
taosMemoryFree is not declared in taos.h for application to compile, and not exported in taosc's windows port for application to use.
and taosMemoryFree is not trivial implemention of free

as a result, functions, such as taos_stmt_get_tag_fields/taos_stmt_get_col_fields, would result in memory leakage in application.

Describe your desired behavior
no memory leakage in application built upon taos.h/taosc

Describe your solutions/suggestions if you've any
either declare and export taosMemoryFree or add specific API in taos.h for application to use.

Additional context
seems all versions of taos suffers

@freemine we don't need to export taosMemoryFree, you can call free to free the memory. taosMemoryFree also calls free directly.

@dapan1121 have you tried in windows port with free directly?

@dapan1121
how should i say.
after a lot of tweeks, guess what?
following official document, taosc is built with Debug configuration, which finally links Debug version of free
but the application is build with Release configuration, which links Release version of free.

when i rebuild application in Debug configuration, problem disappears.

this is the root cause.

frankly speaking, a specific API better be there in taos.h publicly for application to use!
