Reference targets to addr of a `count`/`for_each` instance won't be collected

[magodo]

The CollectReferenceOrigins and CollectReferenceTargets are not recognizing references who targets to an address of a block instance with count/for_each.

Close in favor of hashicorp/terraform-ls#1840, as the count/for_each are not HCL general.

Reopening this issue as I saw the hcl-lang do have handling of the count and for_each:

hcl-lang/decoder/reference_origins.go

Lines 131 to 134 in f5c7d04

	if bodySchema.Extensions != nil && bodySchema.Extensions.Count && attr.Name == "count" {
	aSchema = schemahelper.CountAttributeSchema()
	} else if bodySchema.Extensions != nil && bodySchema.Extensions.ForEach && attr.Name == "for_each" {
	aSchema = schemahelper.ForEachAttributeSchema()
