[nrf fromlist] soc: nordic: nrf54h: generate PERIPHCONF macros based on devicetree

Upstream PR #: 95915

Add a script that makes the build system able to generate macros for
populating the PERIPHCONF (global domain peripheral configuration),
based on nodes and properties found in the devicetree.
The script does the same job as nrf-regtool did when building for
nrf54h20 before the move to using IronSide SE, and should make it
so all samples and tests that were broken by that move now
function correctly without workarounds or manual steps.

The script will also be used on nrf9280, therefore it is placed in
the common uicr directory.
