Relates to #15795

Previously we had not been evaluating the default value of a coder_parameter before extracting the tags. This PR adds support for dynamic default values from a variable.
It does not add support for 'chaining' parameter default values, as I could imagine us ending up in a situation where we have a cyclic dependency.

defaultsM[dataResource.Name] = strings.Trim(value, `"`)
// Issue #15795: the "default" value could also be an expression we need

// TODO: should we support coder_parameter default values that reference other coder_parameter data sources?

Has there been an ask? If not, we can probably defer it until such a time. It's best to be careful how much we expand the scope of these expressions.

I'm not aware of any ask for this just yet. I'd much prefer to defer it as it opens up several cans of worms.

It is sort of a FIXME :)

resource "foo_bar" "baz" {}
variable "region" {
type = string
default = "us"

I don't remember the current bevahior, so let me ask -
how this solution will perform if we have a variable without a default value? AFAIR Coder should require to input the value for variable.

Correct, if there is no default value we will fail this 'preflight' check with an error. This only happens if you're using the coder_workspace_tags data source.
