v1.27.0

This update pulls in Buildroot 2024.02. This is a major Buildroot update.

Nerves systems need the following updates:

1. For Raspberry Pi systems using libcamera, the version that comes with Raspberry
   Pi OS has diverged from upstream libcamera. To use it, replace
   BR2_PACKAGE_LIBCAMERA_*=y with BR2_PACKAGE_RPI_LIBCAMERA_*=y.
2. The Raspberry Pi applications for libcamera also changed. Replace
   BR2_PACKAGE_LIBCAMERA_APPS=y with BR2_PACKAGE_RPICAM_APPS=y. The upstream
   package is called rpicam_apps. libcamera_apps was the old name.
