[ci] reduce workflow job runtimes to under 30 minutes (#13761)

Several GitHub Actions jobs (`Build` `gcc-*`/`clang-*`/`macos-*`,
`POSIX` `expects-linux`, `Simulation` `expects`, `OTNS` `Stress
connectivity`, and `CIFuzz`) previously serially executed dozens of
clean CMake builds or real-time `expect`/stress/fuzz tests in a single
job, taking 30 to 75 minutes and slowing down PR turnaround.

This commit splits those serial build and test steps into parallel jobs
and tunes stress/fuzz durations so individual jobs average under 30
minutes without dropping any build configurations or test cases:

- `build.yml` + `script/check-simulation-build*` +
  `script/check-posix-build`: Split simulation CMake builds into two
  balanced groups (`1.1` and `1.4`, 11 builds each) and POSIX CMake
  builds into `posix` and `posix-daemon` (7 builds each on Linux). Run
  `simulation-1.1`, `simulation-1.4`, `posix`, and `posix-daemon` as
  separate matrix jobs for Linux `gcc`/`clang`, and `posix`,
  `simulation-1.1`, and `simulation-1.4` for `macos`.
- `posix.yml`, `simulation.yml`, + `script/test`: Support filtering
  `expect` tests by category via `OT_EXPECT_CATEGORY`, splitting
  `expects-linux` into `expects-posix-cli`, `expects-posix-rcp`, and
  `expects-posix-tun`, and `expects` into `expects-cli` and
  `expects-non-cli`.
- `otns.yml`: Reduce `connectivity` stress level from 6 to 3 to align
  its runtime with the other OTNS stress suites.
- `fuzz.yml`: Reduce `fuzz-seconds` from 1800 to 900. CIFuzz on pull
  requests is a quick regression check (OSS-Fuzz's default
  `fuzz-seconds` is 600s) that only fuzzes targets affected by the PR
  against the existing OSS-Fuzz seed corpus and crash regressions,
  whereas deep continuous fuzzing of `main` already runs 24/7 on
  Google's OSS-Fuzz infrastructure.
