RFR: 8354560: Exponentially delay subsequent native thread creation in case of EAGAIN [v3]

[Yannik Stradmann]

> This change introduces an exponential backoff when hitting `EAGAIN` during native thread creation in hotspot.
> 
> In contrast to the current solution, where we retry to create a native thread up to three times in a tight loop, hotspot will will thereby be more kind to an already depleted resource, reduce stress on the kernel and become more robust on systems under high load.
> 
> The proposed modifications to `os_linux.cpp` have substantially improved system stability in a mid-sized Jenkins cluster and have been in production within our systems over the past three years. I have verbatim ported these to the other platforms, which previously also relied on identical logic.
