lang/funcs: Switch fileset() function glob implementation to github.com/bmatcuk/doublestar to support additional glob patterns
This allows the usage of the glob patterns `**` and `{alternative1,...}` to simplify Terraform configuration logic for more complex file matching.

lang/funcs: Update fileset() function to include path as separate first argument, automatically trim the path argument from results, and ensure results are always canonical with forward slash path separators
Reference: https://github.com/hashicorp/terraform/pull/22523#pullrequestreview-279694703

These changes center around better function usability and consistency with other functions. The function has not yet been released, so these breaking changes can be applied safely.

lang/funcs: Add fileset function
Reference: https://github.com/hashicorp/terraform/issues/16697

Enumerates a set of regular file names from a given glob pattern. Implemented via the Go stdlib `path/filepath.Glob()` functionality. Notably, stdlib does not support `**` or `{}` extended patterns. See also: https://github.com/golang/go/issues/11862

To support the extended glob patterns, it will require adding a dependency on a third party library or adding our own matching code.
