[Regression] False positive type check for method arguments with defineExpose

[ahnpnl]

Summary

vue-tsc shows false positive type check for this piece of codes

<script setup lang="ts">

interface Bar {
    foo(bar: string): void;
}

defineExpose<Bar>({
    foo(bar) {
        console.log('foo', bar);
    }
})
</script>

The error is error TS7006: Parameter 'bar' implicitly has an 'any' type.

This bug happens since 0.34.15+

Reproduce repo

• Check out https://github.com/ahnpnl/volar-starter-vite/tree/bug/args-type-define-expose (branch args-type-define-expose)
• Install deps with yarn
• Run yarn type-check

Expectation

The error should not be there.

I've found that I still have this bug on 1.8.16, and the version of vue I'm using now is 2.7.14
