debug: tracing: Add Segger RTT and SystemView linker section options

Browse source 
Enables optionally placing Segger RTT and SystemView data in the DTCM
linker section instead of the default data section. This is needed on
SoCs in the i.MX RT series that use cacheable external SDRAM to store
data.
