[mlir][IR] Fix `RewriterBase::replaceUsesWithIf(ValueRange)` in dialect conversion (#172883)
`ConversionPatternRewriter::replaceUsesWithIf` does not support the
`allUsesReplaced` flag and asserts that it's not set. However the
`ValueRange` overload of `RewriterBase::replaceUsesWithIf` always passes
this flag when calling the virtual overload of `replaceUsesWithIf`. This
means calls made to `RewriterBase::replaceUsesWithIf` from a
`ConversionPattern` crash, whether the `allUsesReplaced` flag is set or
not.
This change tweaks `RewriterBase::replaceUsesWithIf` to only pass that
flag if the callee has set it.
