[AOT] Fix warning on dropping const in TVMAotExecutor_GetInputName (#…

…14529)

Prior to this commit, the `TVMAotExecutor_GetInputName` function
accepted a `char** name` output parameter.  When used, assignment of a
`const char*` into `*name` dropped the `const`, resulting in a
warning.  Changing the argument type to `const char**` (pointer to a
mutable pointer to a `const char`) resolves this warning.
