Function that extracts from haystack all matching non-overlapping groups with regular expressions,
and put those into Array(Array(String)) column.

Example:
:) SELECT extractAllGroups('abc=111, def=222, "jkl mno"="444 foo bar"', '("[^"]+"|\\w+)=("[^"]+"|\\w+)');

┌─extractAllGroups('abc=111, def=222, "jkl mno"="444 foo bar"', '("[^"]+"|\\w+)=("[^"]+"|\\w+)')─┐
│ [['abc','def','"jkl mno"'],['111','222','"444 foo bar"']]                                      │
