fix: resolve Fortran benchmark dependencies via manifest.json

- Update `compile_fortran_benchmark` script to dynamically resolve
  Fortran source files (`.f` files) from `manifest.json` using the
  `@stdlib/utils/library-manifest` utility, similar to how
  `compile_c_benchmark` resolves C source files
- Add `resolve_source_files`, `resolve_libraries`, and
  `resolve_libpaths` functions to `compile_fortran_benchmark`,
  matching the structure of `compile_c_benchmark`
- Revert `blas/base/dger` Fortran benchmark `Makefile` to remove
  hardcoded path to `xerbla` dependency; the build script now
  resolves the dependency via `manifest.json`

Closes: stdlib-js#11333
