Files.Lines guards against a nil entry but an empty file inside a
chart is stored as a non-nil zero-length byte slice, so the trailing
newline check indexes s[-1] and panics. The engine recovers the panic
into a render error, making every template/install/upgrade/lint that
references the file fail.
Extend the guard to len(f[path]) == 0 and return an empty slice,
matching the behaviour for missing files.
Fixes#32279

Linting is specific to the chart versions. A v2 and v3 chart will
lint differently.
To accomplish this, packages like engine need to be able to handle
different chart versions. This was accomplished by some changes:
1. The introduction of a Charter interface for charts
2. The ChartAccessor which is able to accept a chart and then
provide access to its data via an interface. There is an
interface, factory, and implementation for each version of
chart.
3. Common packages were moved to a common and util packages.
Due to some package loops, there are 2 packages which may
get some consolidation in the future.
The new interfaces provide the foundation to move the actions
and cmd packages to be able to handle multiple apiVersions of
charts.

This change moves the code, updates the import locations, and
adds a doc.go file to document what the v2 package is for.
This is part of HIP 20 for v3 charts

Since Helm is going through breaking changes with Helm v4, the version path to
Helm needs to be updated.

Make template specific functions private to ensure they not misused and
make unit tests simpler. We may export the template helpers later if
needed.
This lays the foundation for the new chart pipeline.
