RISC-V GCC with `-fdata-sections` will emit `.sbss.<name>`, `.srodata.<name>`, and `.sdata.<name>` sections for small data items of different kinds. Clang/LLVM already emits `.srodata.*` sections, and we intend to emit the other two section name patterns in #87040. This change ensures that any input sections starting `.sbss` are combined into one output section called `.sbss`, and the same respectively for `.srodata` and `.sdata`. This also allows the existing RISC-V specific code for determining an output order for `.sbss` and `.sdata` sections to apply to placing the sections.
