perf: skip per-cell block id lookup when no blocks exist
termpty_block_id_get was called once per visible cell per render
frame (~40M times per typical session) even though the block hash
is empty in all workloads without inline images / media cells.
Gate the call on a row-invariant has_blocks flag computed once at
the top of termio_internal_render. No behavior change when blocks
are present.
