Bumps pypdfium2 from 5.1.0 to 5.2.0.

Release notes

Sourced from pypdfium2's releases.

5.2.0

Changes (Release 5.2.0)

Summary (pypdfium2)

• Added new builds android_{arm64_v8a,armeabi_v7a}, {many,musl}linux_{ppc64le,riscv64,loongarch64} and musllinux_armv7l to the release process. This greatly improves platform support. Loongarch is only uploaded to GH, as PyPI doesn't accept it yet. Replaced musllinux_{x86_64,aarch64,i686} with our own builds, as they are a bit smaller than the pdfium-binaries.
• Build s390x this once through emulated gcc, because static clang doesn't seem to produce working builds for this target. We may not be able to continue doing this.
• build_native.py: Added full dependency library vendoring abilities. This is now the default behavior on fallback setup. Integrated ninja/gn bootstrapping helpers.
• CIBW workflow: Use vendored libraries for most Linux targets. Build ppc64le, riscv64, loongarch64 (and theoretically s390x) using static clang that runs on the host architecture (even though from within an emulated container), while being pre-configured for cross-compilation to the target architecture. This is much faster than building with an emulated compiler. Many thanks to Matthieu Darbois (mayeut) of pypa/manylinux for coming up with this approach.
• Greatly simplified verification of pdfium-binaries attestation in pypdfium2's setup. Thanks to Benoît Blanchon for attaching the attestation as artifact.
• Enabled immutability for pypdfium2's GitHub releases, and added build provenance attestations, like pdfium-binaries did.
