  Log Message:
  -----------
  [win/asan] Search both higher and lower in AllocateTrampolineRegion (#114212)

There may not always be available virtual memory at higher addresses
than the target function. Therefore, search also lower addresses while
ensuring that we stay within the accessible memory range.

Additionally, add more ReportError calls to make the reasons for
interception failure more clear.
