arrange() gives meaningful errors

Code
  tibble(x = 1, x = 1, .name_repair = "minimal") %>% arrange(x)
Error <dplyr_error>
  arrange() failed at implicit mutate() step. 
  x Can't transform a data frame with duplicate names.

Code
  tibble(x = 1) %>% arrange(y)
Error <dplyr_error>
  arrange() failed at implicit mutate() step. 
  x Problem with `mutate()` column `..1`.
  i `..1 = y`.
  x object 'y' not found

Code
  tibble(x = 1) %>% arrange(rep(x, 2))
Error <dplyr_error>
  arrange() failed at implicit mutate() step. 
  x Problem with `mutate()` column `..1`.
  i `..1 = rep(x, 2)`.
  i `..1` must be size 1, not 2.

desc() inside arrange() checks the number of arguments (#5921)

Code
  df <- data.frame(x = 1, y = 2)
  arrange(df, desc(x, y))
Error <rlang_error>
  `desc()` expects exactly one argument.
