Remove profiling timeout logic and disable profiling on API 21

[stefanosiano]

📜 Description

removed timeout logic from AndroidProfiler, as unused by the backend anyway, to fix potential profiling always or never running when one times out
removed API 21 from supported profiling versions, due to a crash

💡 Motivation and Context

Timeout logic of AndroidProfiler could make profiling run forever, if a transaction is started after another times out without finishing.
If a profile timed out and the transaction finished, profiling was not started anymore, due to a bug in the logic.
Relay drops timed out profiles anyway, so we don't need to handle them.
Also, profiling crash on API 21, which is 10 years old, so we dropped support for it.

💚 How did you test it?
