Subject: [PATCH 3/3] feat(fast-make): allow shared cache

One may enable the shared cache by setting the following prior to
loading the fast-synthax-highlighting module

```sh
typeset -gA FAST_HIGHLIGHT
FAST_HIGHLIGHT[chroma-make-cache-global]=1
```

This new implementation change the way the cached makefile' parsed
content are expired. Prior to this commit, cached item expired after
7s. The new implementation get ride of the timer limit and
replace it with a good old "is my file content's different"
