Rowan Smith 77522c3945 feat: cli: add support for supplying ephemeral parameters at workspace creation (#26012)
Resolves the issue of `--prompt-ephemeral-parameters` and
`--ephemeral-parameter` not being available for use in the `coder
create` workspace creation command (they are only available in `coder
start` command). Back when they were [added
originally](https://github.com/coder/coder/pull/15030) it seems to have
been an oversight that they were left out.

The problem this solves:

```
coder create --parameter my_ephemeral_parameter=foo
error: prepare build: ephemeral parameter "my_ephemeral_parameter" can be used only with --prompt-ephemeral-parameters or --ephemeral-parameter flag
```

```
coder create my-test-ws -t general --ephemeral-parameter my_ephemeral_parameter=foo
parsing flags ([create my-test-ws -t general --ephemeral-parameter my_ephemeral_parameter=foo]) for "coder create": unknown flag: --ephemeral-parameter
```

Tested on a template with the following:

```
data "coder_parameter" "my_ephemeral_parameter" {
  name         = "my_ephemeral_parameter"
  type         = "bool"
  description  = "true or false?"
  mutable      = true
  default      = false
  ephemeral    = true
}

resource "coder_env" "debug_ephemeral" {
  agent_id = coder_agent.main.id
  name     = "EPHEMERAL_TEST"
  value    = data.coder_parameter.my_ephemeral_parameter.value
}
```

By running:

```
➜  coder git:(rowan/coder-create-5495) ✗ go run cmd/coder/main.go create --ephemeral-parameter my_ephemeral_parameter=true
> Specify a name for your workspace: ws4
Select a template below to preview the provisioned infrastructure:
?  kasmvnc-ubuntu-coder-dev used by 1 active developer
Select a preset below:
?  Small (2 CPU / 4 GB)
....
...
The ws4 workspace has been created at Jun  3 12:36:38!

➜  coder git:(rowan/coder-create-5495) ✗ coder ssh ws4               
workspace-ws4-5d6994756f-qlwnl% echo $EPHEMERAL_TEST
true
workspace-ws4-5d6994756f-qlwnl% exit
```
