cmake: hardcode git info for faster incremental Debug builds

[battlmonstr]

Problem:

A git commit sha or a branch name change causes relinking of executable targets with silkworm-buildinfo library even if nothing else has changed.

During development (e.g. local Debug builds) it is more important to have fast incremental builds than having the correct git commit sha and a branch name baked into the binary.

Solution:

Add git info arguments to cable_add_buildinfo_library. Hardcode them in Debug builds to avoid relinking and save time when doing small changes and git rebase/squash/reword operations.

Test

Silkworm git commit --amend --date=now && time make output before the change:
