Most SIMDe functions have the SIMDE_ or simde_ prefix internally.
Several of the ARM hash functions do not have this prefix, and this
means that the standard names of ROR32/ROL32 can conflict with other
projects using the library.

This is purely a cosmetic change with internal function renaming.  It
changes no external interfaces, simply removes a source of potential
conflict with other projects that have similarly named macros.
