Every VideoCommon message goes through the printf log and alert macros,
PRIM_LOG included; a register field or an enum in a message is printed
as its number.
The names built along the way no longer go through fmt:
- a texture's name parts (its size, hashes and format) are formatted
into buffers on the stack, and the wildcard names concatenated;
- an EFB or XFB copy's name and dump path are made by one helper, from
an id formatted on the stack;
- dump paths, graphics mod paths and group names are concatenated;
- the projection lookup key is formatted on the stack, on the heap only
when a name runs past it, as before;
- the format overlay draws TextureFormatName, a constant string.
The no-op LOG_NORM and LOG_VTX macros, commented out since they were
added, are gone. The register formatters in the headers stay until the
assertions move over.
