Codechange: use SetDParam for tooltips

[rubidium42]

Motivation / Problem

The tooltip code has code to manually set parameters for its strings, which yields things like params[1] = (size_t)details.c_str();, but it also allows using SetDParam/SetDParamStr but then has a custom implementation for copying the data.
So why not unify it to SetDParam/SetDParamStr and CopyOutDParam, like the other functions handling string formatting parameters?

Description

Replace the params with SetDParam/SetDParamStr.
Remove the unneeded params parameter.
Replace customer parameter copying with CopyOutDParam.
Reorder arguments to tooltip function, because the close condition is essentially always set whereas the number of parameters is way more often just 0.

Limitations

None.
