Remove op_new_captured_func
​https://bugs.webkit.org/show_bug.cgi?id=137491

Reviewed by Mark Lam.

Removes the op_captured_new_func opcode as part of the work
towards having any magical opcodes that write directly to
named "registers" and then have a follow on op to ensure that
the environment record correctly represents the stack state.

For this we add a non-captured scratch register so we don't
have to have any kind of magic opcode, and instead simply
have sensible creation and move semantics for capturing new
functions.
