Using the smartparens package, sp-splice-sexp-killing-backwards does
that. Consider the following examples (where | indicates point):

(insert (|format "Some string")) ==> (insert |format "Some string")

(insert |(format "Some string")) ==> |(format "Some string")

paredit (and I assume lispy) have similar commands, but they only work
in Lisp modes. smartparens handles any kind of delimiters, also quotes
etc. and can work in non-Lisp modes as well. For example, I can do the
transformations above in the buffer I'm writing this message in, which
has `message-mode` as its major mode. And I use it sometimes to
transform footnotes in LaTeX into normal text.
