forth: Replace "SKIP?" with "(?br)"
...
There is an alternate git history where I continued the Forth-ification of
words, including "SKIP?", but that was a bad idea: because that word was
written by flow control immediates, I stepped into quicksands where stability
became necessary in z80c.fs and I couldn't gracefully get out of it.
I'm stepping back and take this opportunity to replace the shoddy SKIP? algo
with a more straightforward (?br) implementation.
(br) and (?br) will always stay in boot code where it's easier manage a stable
ABI.

They do save space (nearly 100b), but they complicate our Forth-ification

This allows us to save a whole 500 bytes on the final binary size!
This change comes after I took a look at the hex dump and saw that one letter
constants in z80a.fs took a lot of space.
