JIT: three fixes for OSR (#62367)

Found when trying to enable OSR by default and prospecting for arm64 support.

* Explicitly initalize the OSR step variable.
* Prevent `fgOptimizeUncondBranchToSimpleCond` from changing the scratch entry
  BB to have conditional flow.
* Retain runtime supplied patchpoint info when cleaning up after an altjit failure.
