Fuzzers like to generate silly long source, and formatting large spans of these can take considerable time.
Only format the diagnostic if it is going to be displayed.
Significantly speeds up some fuzzing tests, fixing some timeouts.
Also add a minor optimization to the formatter repeat() implementation.

Spvtools recently added support for the vkdebuginfo instructions,
causing roll failures since Tint build files didn't generate the
headers for them. Instead of adding more generator stuff in Tint's
BUILD.gn files, this commit removes everything in favor of directly
referencing spvtools' targets.
In follow-up work, the references to spvtools_internal_config will
be changed to a more narrowly scoped target so that spvtools'
warning suppressions don't get propagated to Tint.

Setting precision to `std::numeric_limits<float>::max_digits10` is valid
when using the `scientific` floatfield format when printing values.
However, we used `fixed` to make our floats more human-readable. This
change keeps the output in `fixed`, except if doing so loses precision,
in which case we fall back to `scientific`.
This fixes the rendering differences seen in the Babylon.js examples
(https://crbug.com/tint/944) between Dawn using Tint vs SPIRV-Cross, as
Tint's output was emitting values that had lost too much precision
(e.g. very small numbers being output as 0).
