    linux-firmware: rename packages for i915 firmware
    
    Change the package name from intel-igpu-firmware-* to i915-firmware-*,
    the prefix "intel-igpu" is misleading, i915 firmware is not only for
    iGPU but also for dGPU now.
    
    Remove the redundant "intel" as i915 is already well known.
    
    More accurate file classification to handle following files correctly:
    
      adlp_dmc.bin
      mtl_huc.bin
      mtl_huc_gsc.bin
      mtl_gsc_1.bin
    
    The pattern in regex is "([[:alnum:]]+)_([[:alnum:]]+)(_[\w-.]+)?\.bin",
    where $1 is the platform, $2 is the firmware type (dmc, guc, huc, etc.),
    and the optional $3 which is revision or other suffix.
    
    Glob first to narrow down the target file set, and then split with "_"
    to extract the firmware type (remove the ".bin" in case there is no $3)
    
    Add package "i915-firmware" as a meta package to install all the i915
    firmwares, it is a balance between simplicity and optimization.
    
    * Installing all the available firmwares as a whole, can support all the
      platforms, not only the current one but also the future ones. The
      price to pay is the increased size.
    * If we want to minimize the storage, we can customize to install the
      necessary ones only, even for the target platform only (e.g. ADL) and
      skip the others. The price to pay is the time to tune.
    
    What I am going to do is:
    
    * Let drm-i915 driver depend on i915-firmware-dmc, which is small and
      can cover most of the old platforms
    * Let the user select i915-firmware to install all the i915 firmwares as
      a whole to cover the latest or future platforms
