Add support for KR260

[JoniSt]

Initial support for the Kria KR260 (K26 SoM + carrier board).

This also adds:

• Support for Vivado 2025.1 and vitis-run (replacement for vitis_hls)
• Support for linux-xlnx 2024.2 and 2025.1 in toolflow/boot
• The ability to specify carrier board connections in a platform JSON
• squashfs configs to allow users to install the Xilinx snap package on their boards
• Debug output in FSBL

Fixes:

• Missing dma-coherent tag on the tapasco device (VFIO refuses to bind without it on newer kernels)
• Broken globs in the SD image build script (kernel modules / headers installation)

Some remaining issues with the code in this PR:

• common_2025.1.tcl (and 2025.1.1) might have some wrong IP block versions since I'm missing some IPs in my local (free) Vivado install
• The vitis-run support added in 41cf3f0 needs some work to fix logging
• The commit history is a bit messy, this needs an interactive rebase or just squash on merge
• Might also need a rebase onto the develop branch
