Don't disable folly tracepoints on Android

Summary:
Folly tracepoints were initially disabled on Android in D13293303 landed in 2018 when only x86 tracepoints were supported. D57171286 landed in May 2024 added support for aarch64 tracepoints, but remained disabled on Android by default.

This diff removes the no longer unnecessary flag and enables tracepoints by default.

Reduce duplication between `TaskPromise` specializations

Summary: Make the `TaskPromise<>` leaf classes as simple as they can be. This shortens the code by 30 lines, and makes it easier to follow.

Create an enum for superconsole interaction toggles

Summary:
Current implementation of console toggles relies on `char` and display is error-prone (.e.g we forgot to add `x` option to the Help). I initially tried to fix this in D60960924 but then realized that this could happen in the future. Better to make it type-safe so that we get it for free (via `strum::EnumIter`).

Also rename  `ConsoleInteraction` to `SuperConsoleInteraction`  to signify that these only for for superconsole.

simplify cache local/lifetime coordination in SingletonRelaxedCounter

Summary:
Rather than giving up on constraining the cache thread_local local and cache thread_local lifetime to be in the same DSO, now constrain it and assert on the constraint. This allows the cache thread_local local and the cache thread_local lifetime to be 1:1 with each other, rather than M:N with each other without the constraint.

Note that there is now no cross-DSO merging of these thread_local variables - they are now explicitly per-DSO.

folly: fix github ci tests on macos arm (facebook#2253)

Summary:
These were [failing on github](https://github.com/facebook/folly/actions/runs/9923539774/job/27413784309#step:48:6919)

I think the problem was the macos runner changed from intel to arm, expectations needed updating for arm.
