Fix broken chips on timelin eActivity on show pages (#9057)

We were using RecordIndexContext in FieldDisplays components which is
wrong as the FieldDisplays could be used in locations not providing this
context (not being indexes pages).

Instead, we are passing it within FieldContext which the context that
will always be there for FieldDisplays and we need indexes to fill this
FieldContext with their RecordIndexContext value when needed
