Codechange: minor bits and pieces related to fmt::format() (#11806)

- Don't make run-time formatting what can be done compile-time.
- Be explicit about run-time formatting.
- Fix datetime printing.

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

Codechange: Use std::array for GRF(File|Config) parameters.

This simplifies comparison, copying and assignment operations.

Codechange: Place gamelog into its own class, along with internal data.

Data is now stored in vectors to avoid manual memory management and
passing lengths around.

Codechange: [core] Implement SmallVector using std::vector

The public and protected interface to SmallVector are unchanged
SmallVector now requires that items be default constructible
This isn't an issue since some contained items were previously created
uninitialized.

Temporary default constructors are added to the following structs
- SmallPair
- SmallStackItem
- GRFPresence

Where vector<bool> is required, transition immediately to std::vector
to avoid returning proxy object references.

(svn r16269) -Codechange: use gcc's ability to check parameters sent to printf-like functions
-Fix: wrong number of parameters or wrong parameter types sent to printf-like functions at several places
