toolchain: revert workarounds and fix regressions in bumping

[BugenZhao]

Too many workarounds are introduced when bumping toolchain to 2022-10-16 in #6025, including unnecessary dyn, unsafe and unnecessary allocation. We should revert them as soon as possible.

• storage: fix file cache lifetime issues #6086
• streaming: fix hash join degree table scan #6087
• revert workarounds in deterministic scaling test #6864
• large number of obligation produced in async code causing compiler stuck rust-lang/rust#103423
• performance regression (for debug & single binary) of backtrace capturing after bumping toolchain on macOS #6131
  • bug(debug profile): segfault/EXC_BAD_ACCESS during backtrace capture #6205
  • capturing stack backtrace becomes slower and sometimes segfaults on Apple Silicon rust-lang/rust#104388

It's 2022-10-16 indeed. Wrong title for the previous PR.

Let's close this and leave #6131 alone. It seems not a compiler frontend stuff.
