* tests splitted, phase 1

* typo

* fix wrong launch commands

* typos

* rearrangements

* use `nproc` function for threads

* use nproc for threads

* let theads be auto, build-andriod no more in regular run

* split val chain and cargo check

* renamed some files

* wrong phase

* check rust files before test jobs

* lint error

* rust files modivied var

* test except changes

* add rust_changes except

* lint error

* fixes

* .gitlab-ci.yml can't be excluded

* pipeline shouldn't start

* pipeline must go

* pipeline must go 2

* pipeline must go 3

* pipeline must go 4

* pipeline must go 5

* pipeline must go 6

* pipeline must go 7

* pipeline must not go 1

* pipeline must go 8

* avoid skippng tests yet, reintroducing them after the caching
