modules: wiseconnect: kernel sleeptimer bug fix siwx91x

The fix resolves the drift test failure as part of kernel
timer behaviour and timer api test suite.
Moved sleeptimer-related source files to RAM using zephyr_code_relocate
when CONFIG_SILABS_SISDK_SLEEPTIMER is enabled, and removed duplicate
listing from PMGR backend.Updated Kconfig to select SRAM_VECTOR_TABLE
and CODE_DATA_RELOCATION_SRAM for the sleeptimer service.
