Subject: [PATCH] [RISC-V] Fix ProcessWaitingTests.WaitChain and
 ProcessWaitingTests.WaitAsyncChain

Since WaitChain and WaitAsyncChain test cases perform quadruple nested chain of corerun invocation,
and rely on execution time, they are pretty sensitive to corerun startup time. On RISC-V we experience test failures
due to the fact that WaitInMS timeout is too aggressive for Checked and Debug builds in the case of R2R absence.
It seems that without System.Private.CoreLib R2R artifacts CoreCLR need to jit 2x-3x more functions (Checked build).
We think it's reasonable to expect tests working even in case of lack of R2R.
This change fixes mentioned test cases by bumping waiting timeouts for RISC-V architecture.
