Set ChartDir only for directory-based charts to enable $ref resolution in
JSON schemas. Archived charts (.tgz) are loaded into memory without filesystem
extraction, so $ref resolution is not supported for them.
This fixes the original issue where `helm template .` and `helm install .`
failed to validate schemas with relative $ref references.

Schema validation with $ref cross-file references only works when charts
are available as directories on the filesystem. The install, template, and
upgrade commands may work with archived charts (.tgz) that are loaded
directly into memory without filesystem extraction.
This change limits ChartDir setting to the lint command only. The lint
command already extracts archived charts to temporary directories before
validation, so $ref resolution works for both directory and archived charts
when linting.
For install/template/upgrade commands:
- Main schema validation continues to work
- Charts without $ref validate successfully
- Charts with $ref will fail .. maybe we could add a warning about $ref not being supported in these commands?
Changes:
- Remove ChartDir assignment from install and upgrade commands
- Update schema validation to use synthetic path when chartDir is empty
- Add test for linting archived chart with $ref
- Remove install/template/upgrade tests for $ref (not supported)

Extends JSON schema validation to support relative $ref imports
across helm lint, install, template, and upgrade commands.
Addresses George's review comments:
- Pass chartDir directly instead of deriving from valuesPath
- Create new functions instead of changing public API signatures
- Use absolute file paths for proper URL-based $ref resolution
Implementation:
- Added ValidateAgainstSchemaWithPath to resolve $ref using
absolute file paths instead of root-relative URLs
- Thread chartDir through Install/Upgrade structs and all
validation functions
- Updated both v2 (public) and v3 (internal) lint rules
Fixes relative $ref resolution when running commands like:
helm lint ../sample-chart
helm install release ../sample-chart

This change is about handling the interfaces to public functions for
different chart apiVersions. The internals are still focused on v2.
This enables v3 to be layered in layer.

A few things are added here:
1. The cache is made to be more generic as a content based cache.
It could be used for other things such as plugins
2. Flags were added to specify the content cache locaiton rather
than rely on the repository cache. Keeping the 2 the same
hid bugs and errors.
3. Tests were added and updated to ensure the cache is used and
tested
