```
std.Progress: move global preallocations to thread memory

Instead of making static buffers configurable, let's pick strong
defaults and then use the update thread's stack memory to store the
preallocations. The thread uses a fairly shallow stack so this memory is
otherwise unused. This also makes the data section of the executable
smaller since it runtime allocates the memory when a `std.Progress`
instance is allocated, and in the case that the process is not connected
to a terminal, it never allocates the memory.

```
