While the constructor is not used by Helm itself, it is used by SDK
users and there is currently no alternative way to expose this.

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

chartutil was originally created to operate on protobufs which are
no longer part of Helm. The util package makes more sense to be
part of the chart package.
This change is part of the HIP 20 to create v3 charts and
explicitly call out v2 charts. The changes for this are in smaller
bite size changes.

Introduces two new template functions that marshal data to YAML and
JSON, respectively, and panic on errors. This allows for strict
validation of template output formats.

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

Multiple changes were made to pass linting. Some Go built-in names
are being used for variables (e.g., min). This happens in the Go
source itself including the Go standard library and is not always
a bad practice.
To handle allowing some built-in names to be used the linter config
is updated to allow (via opt-in) some names to pass. This allows us
to still check for re-use of Go built-in names and opt-in to any
new uses.
There were also several cases where a value was checked for nil
before checking its length when this is already handled by len()
or the types default value. These were cleaned up.
The license validation was updated because it was checking everything
in the .git directory including all remote content that was local.
The previous vendor directory was from a time prior to Go modules
when Helm handled dependencies differently. It was no longer needed.

This covers:
- `tpl` text can `include` a `define` provided in a partial file
- `tpl` text can `include` a `define` provided in its text
- `tpl` text can be loaded via `.Files.Get`

- Use a clone of the current Template instead of re-creating everything from scratch
- Needs to inject `include` so any defines in the tpl text can be seen.

This is a regression accidently introduced in #9957.
A delete call had been used on the Template key of vals. This caused
a condition where Template was not available when rendering via tpl.
The delete happened after ExecuteTemplate so the issue is surpsising.
It may possibly be a race condition. Existing tests did not catch it.
I tried to create a test that directly tested the issue and was
unable to replicate the error seen with real charts. This leads me
to believe it is a race condition in the underlying Go template
package.
The delete call was not there before #9957. It should be safe to
remove and keep that information.

The templating engine handles errors originating from the `required` and
`fail` template functions specially, cleaning up the error messages to
be more presentable to users. Go's text/template package unfortunately
does not make this straightforward to implement. Despite
template.ExecError implementing Unwrap, the error value returned from
the template function cannot be retrieved using errors.As. The wrapped
error in ExecError is a pre-formatted error string with the template
function's error string interpolated in with the original error value
erased. Helm works around this limitation by delimiting the
template-supplied message and extracting the message out of the
ExecError string with a regex.
Fix the parsing of `required` and `fail` error messages containing
newlines by setting the regex flag to make `.` match newline characters.

Note, there is an issue with a dependency of sprig changing
behavior. A test has been added with a description to catch if a
behavior breaking change of mergo is used.
See https://github.com/imdario/mergo/issues/139 for the mergo
issue and sprig for further details on handling this in the
future.
