morris 89ce14eaee feat(cordic): share the engine with acquire/release 
The hardware is a singleton, so the driver now hands out references
instead of exclusive creates. new/delete stay as a deprecated pair.
csr_cfg is programmed in one RMW, and the wait path no longer queries
the RTOS tick on every poll.

morris f5afb99e3b fix(gdma): treat burst size 0 and 1 as burst disabled 
The GDMA layer used `max_data_burst_size == 0` as the only way to disable the
data burst. That conflicts with the upstream drivers' convention where a zeroed
config struct means "unset", so users had no way to ask for the driver default
burst size.

GDMA now treats both 0 and 1 as "no data burst": a single-beat burst has no
benefit over the non-burst mode. The MSPI alignment constraint under Flash
Encryption / PSRAM ECC still takes precedence and is reported with a warning.

The upstream drivers using GDMA now apply their own default burst size (16
bytes) when the user leaves `dma_burst_size` as 0, following the UHCI driver:

- esp_async_crc (AHB / AXI GDMA backend)
- esp_async_memcpy (AHB / AXI / LP-AHB / DW_GDMA backend)

Callers that really want no burst can now set `dma_burst_size` to 1.

morris 85680029d2 refactor(i2s): replace es8311 example with pcm_player 
Drop echo/recording now that mic_recorder covers capture. The new
example is TX-only and plays embedded PCM on ES8311 or ES8389.

stay in components/ulp.
