  [RISC-V] Update streamer ArchString in emitTargetFeaturePush()

Previously, RISCVAsmPrinter::emitTargetFeaturePush() only emitted `.option push`
and `.option arch` without updating the streamer's active ArchString. When
emitting an ELF object file directly (`-filetype=obj`),
RISCVTargetELFStreamer::emitDirectiveOptionArch() is a no-op while
emitTargetFeaturePop() resets ArchString back to the pushed ArchString, so
module-level inline assembly and functions with custom `target-features` failed
to emit updated `$x<arch>` mapping symbols.

Call RTS.setArchString() with the parsed ISA string in emitTargetFeaturePush()
so `-filetype=obj` records the active `$x<arch>` mapping symbol alongside
`.option arch`.
