Base OS upgrade to Trixie

[saiarcot895]

This is to upgrade the base OS to Trixie. This includes (among other things) the kernel and Docker daemon.

New versions of notable software being brought in:

• Linux 6.12.41
• Docker 28.2.2
• Python 3.13.5
• GCC 14
• Monit 5.34
• OpenSSH 10.0
• Boost 1.83
• Bash 5.2.37
• Various python dependencies updated to newer version or being pulled from Debian repos instead of pypi

Release notes:

• For applications using sysfs to access i2c devices, /sys/class/i2c-adapter is no longer present. /sys/bus/i2c/devices can serve as a replacement.
• With the Monit upgrade, the wording of the good/success case for checks have changed; specifically, it is now consistently OK for all types of checks.
• Cgroups v1 has been disabled, in place of v2. This allows Docker to track disk and network I/O for containers, and can allow for more fine-grained resource tracking.
• pam_systemd is now used. This means that each user that's logged in will have a user instance of systemd running, resource limits may apply to user sessions, and a cgroup will be created for each user session.
• systemd-sonic-generator has been modified to not touch any service files in /etc or /usr/lib. Systemd no longer allowed service generators to modify any files outside of directories that it explicitly specifies.
• libyang v1 is now built as part of the SONiC build, as it has been removed from the Debian repos.
