Changes

trx: add JSON stats export for WebSDR API

Introduce stats_json.c providing JSON serialization for:
- stats and counters
- rate counters
- BTS state
- TRX/transceiver state
- WebSDR runtime metrics

Add osmobts_get_stats() API to expose these via WebSDR
interface and export it in Emscripten build

This enables programmatic access to data previously available
via VTY (e.g. "show stats", "show bts")

Change-Id: Ifb82adfab879a65ecd222c45e06551983aa90a0f

trx, bts: add optional WebSDR backend (callback-based transport)

Introduce WebSDR backend enabled via ENABLE_WEBSDR,
adding an alternative callback-based transport alongside
existing socket-based TRX/OSMUX I/O

Implement:
- TRX control via osmotrxlib_process_command()
- TRXD data via apitrx_tx_call()/trx_data_read()
- clock handling via apibts_clock_ind() and external timers
- Osmux integration via ws_osmux_* helpers

Adapt scheduler to support API-based burst submission and
external timer callbacks in WebSDR mode

Disable signal handling, stats and socket I/O when building
with ENABLE_WEBSDR

Add WebSDR API entrypoint, Emscripten build target and
example configuration

Enables running BTS/TRX stack in WebAssembly environments

osmo-bts-omldummy: properly report NM_ATT_IPACC_SUPP_FEATURES

osmo-bts-omldummy is used as the OML backend in the ttcn3-bsc-test.
The common OML code encodes bts->support.* and trx->support.* fields
verbatim into the IPA Supported Features IE (NM_ATT_IPACC_SUPP_FEATURES)
in Get Attributes Responses.  Since bts_model_init() and
bts_model_trx_init() never initialized these fields, they were reported
as all-zeros to osmo-bsc.

osmo-bsc now inspects the supported channel modes before activating a
channel.  An all-zero chan_modes value (present but no bits set) causes
osmo-bsc to reject every speech mode, breaking all assignment-related
TTCN-3 test cases.

Initialize ciphers, gprs_codings, freq_bands, chan_types and chan_modes
to sensible values, matching what osmo-bts-virtual does, so that
osmo-bts-omldummy reports its capabilities correctly.
