feat(tvix): Switch to jemalloc r/8222

Switch tvix to using jemalloc as the default global allocator on
supported (eg, non-msvc) platforms. This gives a pretty reasonable
performance boost basically for free:

int                     time:   [24.361 µs 24.386 µs 24.418 µs]
                        change: [-19.355% -18.859% -18.527%] (p = 0.00 < 0.05)
                        Performance has improved.

                        Performance has improved.

                        Performance has improved.
