build/analysis/importsort: init
This adds an analyzer which enforces import sorting as per
CODING_STANDARDS.md. It is not yet enabled in nogo.
This effectively duplicates some logic that is present in goimports.
However, that logic is mostly within an 'internal' package in x/tools,
and would be somewhat tricky to make work within the framework of an
analysis.Analyser (as it expects to also mutate a file). Thus, we
end up writing the analysis logic ourselves. Tests are provided to make
sure this logic doesn't rot away.
We also move some common logic from 'noioutil' to a new 'lib' package,
and implement the last piece of the puzzle there: a code generator to
provide information about the toolchain's stdlib as a map/set.
