perf: memorize exclude function in webpack config (#81525)
During JavaScript profiling, I identified repeated calls to the exclude
function in the webpack configuration and implemented caching to
optimize it.

I tested the performance using the
[chakra-ui-docs](https://github.com/SyMind/chakra-ui-docs) repository
with the following steps:
1. Execute `pnpm run dev`
2. Wait for the server to be ready (indicated by the 'Ready' message)
3. Run `curl` on the root endpoint (`/`)
