Support debug CPython ABI tags in environment compatibility (#18739)

## Summary

This PR fixes a problem in `uv pip install`, which currently refuses to
install debug wheels in virtual environments with debug CPythons.

Before this change, wheel parsing already preserved debug ABI suffixes
like cp313d and cp314d, but Tags::from_env only propagated free-threaded
and legacy pymalloc variants. As a result, uv would detect a debug
interpreter correctly during discovery while still generating
cp313/cp314 environment tags, causing debug-built wheels to be rejected
as incompatible.

Fix this by accepting a debug_enabled flag in Tags::from_env, mapping it
to CPythonAbiVariants::Debug, and passing the interpreter debug state
from the production call sites in uv-python and uv pip resolution.

Also update the affected tests and helpers, and add a regression test
that verifies debug CPython 3.13 generates cp313-cp313d manylinux tags.

## Test Plan

Tests run:
- cargo test -p uv-platform-tags
tags::tests::test_system_tags_debug_cpython -- --exact
- cargo test -p uv-installer
plan::tests::test_abi3_on_free_threaded_python_hint -- --exact
- cargo test -p uv-installer
plan::tests::test_gil_enabled_cpython_on_free_threaded_python_hint --
--exact
- cargo test -p uv-installer
plan::tests::test_abi3_on_regular_python_no_special_hint -- --exact
- cargo test -p uv --test it
pip_install::abi_compatibility_on_debug_python -- --exact
