[Improvement] Introduce the hcfs spi to avoid mantually specifying gvfs in config

### What would you like to be improved?

Introduce the hcfs spi for gvfs to avoid mantually specifying gvfs in config. Currently the gvfs is needed to specify in config.

### How should we improve?

_No response_

Start by locating the gvfs configuration handling and the existing HCFS SPI entry points or implementations in the repository. Determine how gvfs is currently specified and identify the integration boundary for the requested SPI; done means gvfs no longer needs to be manually specified in configuration.
