feat(cli): add CLI support for creating a workspace with preset (#18912)

## Description 

This PR introduces a `--preset` flag for the `create` command to allow
users to apply a predefined preset to their workspace build.

## Changes

- The `--preset` flag on the `create` command integrates with the
parameter resolution logic and takes precedence over other sources
(e.g., CLI/env vars, last build, etc.).
- Added internal logic to ensure that preset parameters override
parameters values during resolution.
- Updated tests and added new ones to cover these flows.

## Implementation logic

* If a template has presets and includes a default, the CLI will
automatically use the default when `--preset` is not specified.
* If a template has presets but no default, the CLI will prompt the user
to select one when `--preset` is not specified.
* If a template does not have presets, the CLI will not prompt the user
for a preset.
* If the user specifies a preset using the `--preset` flag, that preset
will be used.
* If the user passes `--preset None`, no preset will be applied.

This logic aligns with the behavior in the UI for consistency.

> coder create --help

USAGE:
  coder create [flags] [workspace]

  Create a workspace

    - Create a workspace for another user (if you have permission):

        $ coder create <username>/<workspace_name>

OPTIONS:
      (...)

      --preset string, $CODER_PRESET_NAME
          Specify the name of a template version preset. Use 'none' to explicitly indicate that no preset should be used.

      (...)

  -y, --yes bool
          Bypass prompts.
```

## Breaking change

**Note:** This is a breaking change to the create CLI command. If a
template includes presets and the user does not provide a `--preset`
flag, the CLI will now prompt the user to select one. This behavior may
break non-interactive scripts or automated workflows.
