Improve Linux Consumption cold start (#6408)

Thanks to Bala we got profiles from Linux Consumption for cold starts and noticed we are doing 550msec of JIT
and a big portion of it was because we were still compiling DryIoc in Linux consumption and PGO was not working in Linux becasue of a directory name casing issue.

There is still a big portion of JIT during /admin/instance/assign that we follow up separately.
