Description
Hey there,
I thought it'd be very cool to have a specialisation of the merge function for ComponentArrays, with a similar behaviour as with Dictionarys or NamedTuples.
For instance, consider
N = 2
p = (r = ones(N), b = 3 * ones(N))
p2 = (r = 2 * ones(N))
merge(p, p2) #outputs (r = [2.0, 2.0], b = [3.0, 3.0])
It could be useful to have a similar functionality with p and p2 being ComponentArrays.
I am not sure whether this could be efficiently implemented though.

Research direction
Start by examining the existing merge behavior for Dictionarys and NamedTuples, then trace how ComponentArrays represent named components. Define the expected merge behavior from the provided p and p2 example, including overriding r while preserving b, and verify the result with focused tests for ComponentArrays.
