feat(tvix): Switch to jemalloc

Browse source 
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.

merge small attrs       time:   [37.201 µs 37.328 µs 37.442 µs]
                        change: [-24.609% -24.266% -23.982%] (p = 0.00 < 0.05)
                        Performance has improved.

                        Performance has improved.

                        Performance has improved.
