  [BOLT] Modify warning when --use-old-text fails. NFC (#162731)

When --use-old-text fails, we are emitting all code meant for the
original `.text` section into the new section. This could be more bytes
compared to those emitted under no `--use-old-text`, especially under
`--lite`. As a result, `--use-old-text` results in a larger binary, not
smaller which could be confusing to the user.

Add more information to the warning, including recommendation to rebuild
without `--use-old-text` for smaller binary size.
