Abtin Keshavarzian ea05f9e595 [mac] move CSL period and timeout constants from radio (#13572)
This commit moves `kMinCslPeriod` from `Radio` to `Mac` (`mac_types.hpp`)
and `kMaxCslTimeout` to `Mle` (`mle.hpp`), grouping them logically within
their respective layers.

Key changes:
- Adds `Time::MsecToUsec()` helper function.
- Tightens constant types to native representations: `uint16_t` for
  `kMinCslPeriod` (units of 10 symbols) and `uint32_t` for
  `kMaxCslTimeout` (units of seconds), avoiding narrowing conversions
  across MAC and MLE call sites.
- Bug fix in CSL IE validation: Previously, `Mac::ProcessCsl()` checked
  `csl->GetPeriod() >= kMinCslIePeriod`, where `kMinCslIePeriod` was
  defined directly as `OPENTHREAD_CONFIG_MAC_CSL_MIN_PERIOD` (in
  milliseconds, default 10). Because the CSL IE period field is in
  units of 10 symbols (160 µs), comparing directly against 10 meant it
  was mistakenly validating `>= 1.6 ms` instead of `>= 10 ms`. Replacing
  `kMinCslIePeriod` with `kMinCslPeriod` (which properly converts the
  configured millisecond period to 10-symbol units) fixes this unit
  mismatch bug.
- Updates `Mle::SetCslTimeout()` to validate the timeout against
  `kMaxCslTimeout` and return `Error`, simplifying `otLinkSetCslTimeout()`.
