pgsql: ci: Generate crashlogs on Windows

ci: Generate crashlogs on Windows

This configures cdb.exe to log all crashes to
"<workspace>\crashlogs\crashlog-<pid-in-hex>.txt" (as it was previously set up
for cirrus-ci based CI). The upload logs step already collects these logs.

The logic is copied from the generation of Postgres CI Windows images for
cirrus-ci [1]. Since this would be too long to include inline in pg-ci.yml,
it is implemented as 'src/tools/ci/gha_setup_windows_debugger.ps1' script.
