Update complex constraints in core schema to allow any expressions

[radeksimko]

Context

After introducing AnyExpression as part of #174 we forgot to also update certain parts of the core schema which involve complex type constraints, such as provisioner blocks:

terraform-schema/internal/schema/0.12/provisioners.go

Lines 118 to 125 in 664a8e0

	"inline": {
	IsOptional: true,
	Constraint: schema.List{
	Elem: schema.AnyExpression{OfType: cty.String},
	},
	Description: lang.Markdown("A list of command strings. They are executed in the order they are provided." +
	" This cannot be provided with `script` or `scripts`."),
	},

This means that currently we don't allow interpolation in various places, e.g.

Proposal

Go through all places where we use schema.List, schema.Set, schema.Tuple, schema.Map and schema.Object and check if they need updating to schema.OneOf{} variation, such as

terraform-schema/schema/convert_json_test.go

Lines 191 to 196 in 664a8e0

	Constraint: schema.OneOf{
	schema.AnyExpression{OfType: cty.List(cty.String), SkipLiteralComplexTypes: true},
	schema.List{
	Elem: schema.AnyExpression{OfType: cty.String},
	},
	},
