Only create LazyContentProvider for the non-rendering Site
Which saves a fair amound of allocations:
```
gobench --package ./hugolib --bench "SiteNew/Regular_D" --base master
```
Before:
```
name old time/op new time/op delta
SiteNew/Regular_Deep_content_tree-10 40.7ms ± 3% 41.2ms ± 1% ~ (p=0.343 n=4+4)
name old alloc/op new alloc/op delta
SiteNew/Regular_Deep_content_tree-10 27.7MB ± 0% 28.8MB ± 0% +3.76% (p=0.029 n=4+4)
name old allocs/op new allocs/op delta
SiteNew/Regular_Deep_content_tree-10 304k ± 0% 329k ± 0% +8.07% (p=0.029 n=4+4)
```
After:
```
