By fixing the value of `$ZIG_GLOBAL_CACHE_DIR` to a constant value,
zig builds that embed paths referencing the cache directory are now
fixed, which helps with reproducibility.
This allows users to put zig in their `mkShell` without ending up with a
ZIG_GLOBAL_CACHE_DIR value set that points back to a location that only
would exist in the sandbox.
Most packages that used fetchFromGitea fetch their sources from Codeberg, so might as well migrate them.
The following command was used for this treewide:
```fish
for i in (rg 'fetchFromGitea \{\n *domain = "codeberg.org";' --multiline --files-with-matches)
sed -z 's/fetchFromGitea {\n *domain = "codeberg.org";/fetchFromCodeberg {/g' $i > $i.tmp && mv $i.tmp $i
sed -i 's/fetchFromGitea/fetchFromCodeberg/g' $i
end
```
The following paths were manually edited:
* pkgs/by-name/xr/xrsh/package.nix
* pkgs/applications/networking/browsers/librewolf/src.nix
* pkgs/by-name/go/gotosocial/package.nix
* pkgs/by-name/ka/katawa-shoujo-re-engineered/package.nix

By moving the zig setup hook to the zig derivation itself, we allow for
zig to splice correctly with `callPackage`, meaning that the correct zig
can be pulled in during builds when zig is in `nativeBuildInputs` (for
example).
This change retains the `zig.hook` attribute for backward compatibility
by just pointing to the zig derivation. This also removes
`zig_default_flags`, since now the setup hook is not a derivation that
can be overridden. Overriding the build flags can now be done by setting
`dontSetZigDefaultFlags = true`.
This reverts commit 65a333600d.
This wasn't tested for correctness with something like fodwatch [0],
and should not have been (self-)merged so quickly, especially without
further review.
It also resulted in the breakage of at least one package [1] (and that's
the one we know of and was caught).
A few packages that were updated in between this commit and this revert
were not reverted back to using `rev`, but other than that, this is a
1:1 revert.
