Character length cleanup for Coarray Fortran library

Following the change to use size_t for Fortran character lengths (PR
78534), this patch modifies the Coarray ABI in a similar way. The
single-image implementation that is included in libgfortran is
updated, but this needs corresponding work in the OpenCoarray library
as well for multi-image support. I also fixed the types for the STOP
and ERROR STOP implementation in libgfortran, as the calling of them
is somewhat intertwined with the calling of the corresponding CAF
functions. I'll send the OpenCoarray changes as a separate pull
request to the OpenCoarrays repository.

rs6000: Use brace blocks in define_insn

This patch changes the remaining cases in our machine description files
to use brace blocks instead of double-quoted strings as the output
control string.  This increases readability by making the blocks look
more like normal C code, mostly because backslash quoting is no longer
needed.  It also removes such quoting where it was still there (usually
harmless but always confusing). and it writes "\n\t" as "\;" in one
place where we didn't already.
