Casing is slow and computationally expensive. #1511

Problem
The casing functions in vrl are a bit slow.
. = map_keys(., recursive: true) -> |key| { snakecase(key) }
The above code is equivalent to the code below using upcase in terms of performance.
Low: 0.1ms, High: 0.4ms
I tested using vector playground site. I understand that this method isn't the most accurate in terms of performance but the point I am trying to make is that it doesn't have to be accurate to realize that the casing functions are unoptimized.
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
. = map_keys(., true) -> |key| { upcase(key) }
