## What
Adds a reworked version of webpack's [built-in memory cache garbage
collection
plugin](853bfda35a/lib/cache/MemoryWithGcCachePlugin.js (L15))
that is more aggressive in cleaning up unused modules than the default.
The default marks 1/5th of the modules as "up for potentially being
garbage collected". The new plugin always checks all modules. In my
testing this does not cause much overhead compared to the current
approach which leverages writing to two separate maps. The change also
makes the memory cache eviction more predictable: when an item has not
been accessed for 5 compilations it is evicted from the memory cache, it
could still be in the disk cache.
In order to test this change I had to spin up the benchmarks but these
were a bit outdated so I've cleaned up the benchmark applications.

This PR adds the benchmarking script I've been using for #40251 to
measure the performance improvements that we make to the Edge SSR
runtime.
This tool:
- uploads two version of the benchmarking project to Vercel, one with
the latest canary and the one with your current local changes in dist
(don't forget to build!)
- runs some tests against the published url to measure TTFB
- displays a nice chart and table
What this doesn't do (yet):
- allow you to choose which URL to compare
- allow you to change the measured metric
- run a battery of differnet test
