ci: Introduce CI/CD. Thanks @oxc for your contribution.

This commit is a combination of 6 commits.

chore: typo fix, update docs, make output coherent

fix: quote PAM_WSL_HELLO_WINPATH to allow spaces

chore: increase version, 1.2.0 was already released

build: make builds reproducable

Check-in Cargo.lock to make sure builds always use the same dependency
versions.

perf: decrease pam module binary size

Enable cargo Link Time Optimization, and strip debug symbols from the
binary

build: build with github actions

Requires a little refactoring of Makefiles, so we can build linux and
windows binaries on different machines.
