Commands like `jj log` should accept revsets prefixed with `all:` as a no-op

[Ilya Grigoriev]

Description

Currently, only commands affected by the all: prefix recognize it. This causes confusing syntax errors:

$ jj log -r u

$ jj log -r all:u
Error: Failed to parse revset: ':' is not an infix operator
Caused by:  --> 1:4

1 | all:u
  |    ^

  = ':' is not an infix operator
Hint: Did you mean '::' for DAG range?

We should fix them to accept all: and ignore it.
