[TVMScript] Add block name suffix management for TIR macros (apache#18465)

## Related Issue

closes apache#18344

## Why

When a `T.macro` containing a block was called multiple times in a TIR
function, all expanded blocks had the same name, causing a "Duplicated
block name" error in meta_schedule.

## How

Implemented automatic block name suffixing during macro expansion
