provider-generator: Add support for provider functions

[so0k]

Description

Terraform Provider functions were announced with Terraform 1.8 on April 10, 2024 and I don't see any information about supporting provider functions in terraform-for-cdk.

For example the terraform-provider-aws arn_parse function isn't available (searched using grep in the pre-generated Typescript code).

I believe this affects several components, but it starts in provider-schema component.

terraform-cdk/packages/@cdktf/provider-schema/src/provider-schema.ts

Lines 245 to 250 in 6b78c57

	Object.values(schema.provider_schemas || {}).forEach((provider) => {
	const entities = [
	provider.provider,
	...Object.values(provider.resource_schemas || {}),
	...Object.values(provider.data_source_schemas || {}),
	];

and

terraform-cdk/packages/@cdktf/commons/src/provider-schema.ts

Lines 18 to 22 in 6b78c57

	export interface Provider {
	provider: Schema;
	resource_schemas: { [type: string]: Schema };
	data_source_schemas: { [type: string]: Schema };
	}

Then additional support will need to be lib component to actually use the Provider functions in target languages

@ansgarm @DanielMSchmidt @xiehan - should I attempt working on a PR for this or is this in the works within the cdktf team?
