Nim: Inline NimBuildInfo into nimbuildconfigurationfactory.cpp

It's only used there. Less code, less disk space.

This code is likely to be copied over and over into future language
plugins.
We cannot afford to spend 1 MB of disk space per build for every 12
lines
of trivial code, so remove this precedent.

Before:

1006824 ./.obj/debug-shared/nimbuildinfo.o
1509784 ./.obj/debug-shared/nimbuildconfigurationfactory.o

After:

1520840 ./.obj/debug-shared/nimbuildconfigurationfactory.o
