Defer locals dict allocation for function frames until first access.
Most function frames only use fastlocals and never touch the locals
dict, so this skips one dict heap allocation per function call.
Also remove a redundant code.clone() in invoke_with_locals.
Func call ~23% faster, method call ~15% faster in benchmarks.
Change benchmark interpreter from without_stdlib to with_init to load
Rust-optimized native modules like _json, ensuring benchmarks measure
actual optimized performance rather than pure Python fallbacks.

* Add microbenchmark for `sorted`
I chose 5 * Iterations to try better show that RustPython
sort implementation scales noticeably worse CPython's
with respect to the number of elements.
* Mention how to run a specific benchmark
* Update python version in bench README
3.13 better reflects the current state of the project vs 3.7.
The original hash algorithm just XOR'd all the hashes of the elements of
the set, which is problematic. The CPython algorithm is required to pass
the tests.
- Replace `PyFrozenSet::hash` with CPython's algorithm
- Remove unused `hash_iter_unorded` functions
- Add `frozenset` benchmark
- Enable tests
- Lower performance expectations on effectiveness test
- Adjust `slot::hash_wrapper` so that it doesn't rehash the computed
hash value in the process of converting PyInt to PyHash.
Update the actual benchmark harnesses.
Because the internal APIs previously used are no longer available, I
opted to use `compile` and `exec` from within the CPython context to
compile and execute code. There's probably more overhead to that than
the internal API had, but that overhead should be consistent per
benchmark.
If anyone cares about hyperoptimizing benchmarks then they can optimize
the harness as well.
* list count bench
* Refactor list count avoid duplicate the vec
* optimize list count with HEAPTYPE flag
* introduce generic safe iter functions for list
* Refactor list functions (contains, index, remove)
* Refactor list iter functions with const generics
* optimize list with richcompare
* optimize list iter_equal
