[ui] Add support to initialize projects with templates including CopyOutputs nodes

[cbentejac]

Description

This PR adds an --output argument to Meshroom's command line. By using this argument and providing one or more output paths, Meshroom initializes a pipeline using a template and includes its CopyFiles nodes (if it has any). Previously, CopyFiles nodes were automatically excluded from the pipeline initialization.

This fixes #2934.

Features list

• Add a new newWithCopyOutputs slot that initializes a project from a template and includes the template's CopyFiles nodes.
• Add a new "--output" option to the command line for Meshroom that allows to initialize a project with provided values for the CopyFiles nodes.

Implementation remarks

The newWithCopyOutputs is created as such to be able to initialize a project from a template seemlessly with the error report (through _loadWithErrorReport). This prevents modifying the API to include a copyOutputs boolean that would have to be added everywhere, including in cases where we want to perform a load() rather than a new().
