RRCReestablishmentRequest: add PCI range validation

Browse Source 
Add validation of physCellId against valid range (0-1007) per TS 38.331
specification. Invalid PCI values are now rejected early in the
reestablishment procedure.

This prevents processing of invalid reestablishment requests with
out-of-range PCI values, improving robustness and spec compliance.

Major changes:
- Add NR_PHYS_CELL_ID_MAX to common/platform_constants.h
- Add PCI range check in rrc_handle_RRCReestablishmentRequest() before
  cell lookup, returning early on invalid values
