Semantic token highlighting for variable type declarations

[radeksimko]

Use-cases

Improve accuracy of highlighting via semantic tokens for type declarations via semantic tokens.

variable "test" {
  type = object({
    test_object = map(
      object({
        test_map = string
      })
    )
  })
}

Proposal

Type declarations already seem to be reported by hcl-lang as TokenTypeCapsule and TokenTypePrimitive.

The goal is to choose appropriate LSP token types to translate these into.

	switch token.Type {
	case lang.TokenBlockType:
	tokenType = TokenTypeType
	case lang.TokenBlockLabel:
	tokenType = TokenTypeEnumMember
	case lang.TokenAttrName:
	tokenType = TokenTypeProperty
	case lang.TokenBool:
	tokenType = TokenTypeKeyword
	case lang.TokenNumber:
	tokenType = TokenTypeNumber
	case lang.TokenString:
	tokenType = TokenTypeString
	case lang.TokenObjectKey:
	tokenType = TokenTypeParameter
	case lang.TokenMapKey:
	tokenType = TokenTypeParameter
	case lang.TokenKeyword:
	tokenType = TokenTypeVariable
	case lang.TokenTraversalStep:
	tokenType = TokenTypeVariable
	default:
	return []uint32{}
	}
