across() gives meaningful messages

Code
  tibble(x = 1) %>% summarise(res = across(where(is.numeric), 42))
Error <dplyr_error>
  Problem with `summarise()` column `res`.
  i `res = across(where(is.numeric), 42)`.
  x Problem with `across()` input `.fns`.
  i `.fns` must be NULL, a function, a formula, or a list of functions/formulas.

Code
  across()
Error <rlang_error>
  `across()` must only be used inside dplyr verbs.

Code
  c_across()
Error <rlang_error>
  `c_across()` must only be used inside dplyr verbs.

if_any() and if_all() aborts when predicate mistakingly used in .cols= (#5732)

Code
  (expect_error(filter(df, if_any(~ .x > 5))))
Output
  <error/dplyr_error>
  Error: Problem with `filter()` input `..1`.
  i Input `..1` is `if_any(~.x > 5)`.
  x Predicate used in lieu of column selection.
  i You most likely meant: `if_any(everything(), ~.x > 5)`.
  i The first argument `.cols` selects a set of columns.
  i The second argument `.fns` operates on each selected columns.
Code
  (expect_error(filter(df, if_all(~ .x > 5))))
Output
  <error/dplyr_error>
  Error: Problem with `filter()` input `..1`.
  i Input `..1` is `if_all(~.x > 5)`.
  x Predicate used in lieu of column selection.
  i You most likely meant: `if_all(everything(), ~.x > 5)`.
  i The first argument `.cols` selects a set of columns.
  i The second argument `.fns` operates on each selected columns.
Code
  (expect_error(filter(df, !if_any(~ .x > 5))))
Output
  <error/dplyr_error>
  Error: Problem with `filter()` input `..1`.
  i Input `..1` is `!if_any(~.x > 5)`.
  x Predicate used in lieu of column selection.
  i You most likely meant: `if_any(everything(), ~.x > 5)`.
  i The first argument `.cols` selects a set of columns.
  i The second argument `.fns` operates on each selected columns.
Code
  (expect_error(filter(df, !if_all(~ .x > 5))))
Output
  <error/dplyr_error>
  Error: Problem with `filter()` input `..1`.
  i Input `..1` is `!if_all(~.x > 5)`.
  x Predicate used in lieu of column selection.
  i You most likely meant: `if_all(everything(), ~.x > 5)`.
  i The first argument `.cols` selects a set of columns.
  i The second argument `.fns` operates on each selected columns.
