std.Build.TranslateC: replace addIncludeDir with variants with LazyPath/library names

[paperdave]

addIncludeDir takes a string slice, and does not support LazyPath and other include dir params. To match with Build.Module and Build.Step.Compile, i've adapted the following definitions to TranslateC

• addAfterIncludePath
• addSystemIncludePath
• addIncludePath (changed from "dir" to "path" to match other apis)
• addConfigHeader
• addSystemFrameworkPath
• addFrameworkPath

possible solution for #20649, though motivated by my need to use addIncludePath but it taking a slice.

i haven't thoroughly tested these besides addIncludePath in my own project. i am assuming translate-c supports the same set of flags that build-* supports, and that the existing code for passing the flags works.

Nice, thank you
