riscv: Cache the max alignment of output sections
Cache the max alignment of output sections instead of scanning all
output sections for each input section, which can take a very long
time if there are millions of input/output sections.
PR ld/22274
* elfnn-riscv.c (riscv_elf_link_hash_table): Add max_alignment.
(riscv_elf_link_hash_table_create): Initialize max_alignment to
(bfd_vma) -1.
(_bfd_riscv_relax_section): Cache the max alignment of output
sections if possible.
