Scot Breitenfeld fc12e0b6c1 Declare the H5Zf.c Fortran helpers; apply clang-format 
Two CI failures, both from the preceding commits.

Missing prototypes (hdf5 dev cmake CI). H5Pmodify_filter_by_idx_str_c
and _raw_c were defined in fortran/src/H5Zf.c but never declared in
H5f90proto.h alongside the H5Pappend_filter_*_c helpers. That broke two
different jobs for one reason:

  - "Special Workflows / gcc REL -Werror (build only)" builds with
    -Werror=missing-prototypes and rejected both definitions outright.
  - The Intel and windows-oneapi jobs failed at link with LNK2019 on
    both symbols, because H5FC_DLL on the declaration is what carries
    the dllexport attribute; with no declaration the symbols were never
    exported from hdf5_fortran.dll.

Adding the two H5FC_DLL declarations fixes both. Verified locally by
compiling H5Zf.c with -Werror=missing-prototypes, which the ordinary
build does not enable.

Formatting (clang-format Commit Changes). This job was green on the
commit before this series and has failed on every commit since; the
fault was entirely mine. Ran clang-format 17 -- the version CI pins --
over every file this series touched, C and Java alike, since the check
covers .java here too. The whole tree now passes a local run using CI's
source path and exclusion list.

Full build clean; ctest 3458/3459, the one failure being the
pre-existing ph5_f90_filtered_writes_no_sel example bug fixed upstream
in HDFGroup/hdf5#6633.
