Time domain samples scope for NR UE

Add a new scope data source (ueTimeDomainSamples) which provides time domain samples
for antenna 0 to the scope. Add graphical representation of the data in imscope.

Removed C-define from ENABLE_IMSCOPE cmake option, the #define was unused and this way
code does not have to be recompiled when imscope enable state changes.
