samples: Add radio trims and PAN for nRF54H20 in DTM, RT and ESB

Loading trim values and adding PAN workarounds in the Radio registers will improve RF performance. PANs implemented: HMPAN-18, HMPAN-103. Ref. NCSDK-31274 Signed-off-by: Michał Grochala <[email protected]> (cherry picked from commit 693d1ff)
