Reuses most of the code from BG96. At this moment, this is not a
perfect support for other modules as the generic handlers for most
common modem functionality is not easily reusable. Refactoring to a
fully independent modem component will solve this.
Closes https://github.com/espressif/esp-idf/issues/5250
Also remove event_queue_size from esp_modem_dte_t because
event_queue_size is only used in esp_modem_dte_init.

Signed-off-by: Axel Lin <axel.lin@gmail.com>
Basic set of configuration related to UART moved from KConfig
to runtime configuration structure to simplify reusing the component for
testing and examples.
pppos_client example used the UART default clock configuration which might
cause issues if power management enabled. Settings updated to UART_SCLK_REF_TICK
Also need to explicitly disable RX interrupts in UART pattern detection
mode.

When library users call esp_stop_ppp(), it is expected that the PPP link
is closed and the DCE is moved into command mode.
If the STOP event is not posted into the event loop, then the PPP stack
would not be turned off, resulting in the impossibility to switch into
command mode, as the modem is still sending PPP binary data.
