Fix uv PEX builder to use pex3 lock export (#23227)

When the uv PEX builder extracts pinned requirements from
a PEX-native lockfile, it previously parsed the internal JSON
format directly. This broke VCS and direct URL requirements
(formatted as name==version instead of name @ url), and the
PEX maintainer has warned that this internal format is
unsupported and may change without notice.

This PR replaces JSON parsing with `pex3 lock export --format pep-751`
via PexCliProcess. The exported pylock.toml is passed
directly to uv pip install -r, handling VCS refs, direct URLs,
extras, and platform filtering out of the box.
