2024-10-10: 2712: Add support to override the boot-mode at power on (latest)

Browse Source 
* Introduce a new boot-menu feature where pressing SPACE at power on
  gives the user a one-shot option to select a different boot mode.
  e.g. Select USB boot if the default SD card is corrupted or unavailable.
* Display the bootloader network-install UI for longer on a cold boot to make
  this feature more visible to first time users.
  To revert to the previous behaviour remove NET_INSTALL_AT_POWER_ON=1
  from the bootloader config.
* Support non-UUID HAT mapping
  Extend the HAT map support to allow matching on product and vendor
  strings, as well as product ID and version. As a minimum, there must
  be a product string - if that matches, the other keys are considered.
  Without a product key, the UUID is compared as before.
* Remove requirement for GPT ptable array  to be at LBA-2
  See: https://github.com/raspberrypi/rpi-eeprom/issues/585
* 2712C1 clock manager improvements to slightly reduce idle power ~50mW saving
* Adjust SDRAM page-hold and auto-precharge to improve performance.
  ~2% improvement with Geekbench 6
* armstubs: 2712: Rebuild with updated max-power throttle and direct stream settings
  See: fc45bc492d
* debug: Only display the program_pubkey log if configuring secure-boot
