Add support for "big word" movements in Vim mode #16768
Description
What would you like to be added?
The Vim mode should support the "big word" movements - W, E, and B. These are similar to the already-implemented w, e, and b, but they treat words as only delimited by whitespace, not punctuation.
Why is this needed?
These are important movements. They are supported by Vim (and Bash Vim mode). As a heavy Vim user, I frequently go to use these, and have a poor user experience when they don't work.
