  [lld][ELF] Suppress `--orphan-handling=error/warn` without `SECTIONS` (#93630)

Without a linker script, `--orphan-handling=error` or `=warn` reports
all input sections, including even well-known sections like `.text`,
`.bss`, `.dynamic`, or `.symtab`. However, in this case, no sections
should be considered orphans because they all are placed with the same
default rules. This patch suppresses errors/warnings for placing orphan
sections if no linker script with the `SECTIONS` command is provided.

The proposed behavior matches GNU gold. GNU ld in the same scenario only
reports sections that are not in its default linker script, thus, it
avoids complaining about `.text` and similar.
