  [TableGen][GISel] Remove check for LLT when emitting renderers (#121144)

Types used in the destination DAG of a pattern should not matter for
GlobalISel. All necessary checks are emitted in the form of matchers
when traversing the source DAG.

In particular, the check prevented importing patterns containing iPTR in
the middle of the destination DAG.

This reduces the number of skipped patterns on Mips and RISCV:
```
Mips   1270  -> 1212  (-58)
RISCV 42165 -> 42088  (-77)
```

Most of these patterns are for atomic operations.
