fix(es/minifier): Skip serde of pure_funcs in options (#10969)

**Description:**

The `pure_funcs` is marked as `serde(default)` instead of [`serde(skip)` like `global_defs`](https://github.com/swc-project/swc/blob/v1.13.3/crates/swc_ecma_minifier/src/option/mod.rs#L226),
which leads to the unnecessary import of ecma ast deserialization code.

**BREAKING CHANGE:**

This is a breaking change from an API perspective, but this exposure is
likely accidental and no one uses it.
