host platform: improvements and bugfixes

[clydebarrow]

What does this implement/fix?

Tweaks to make the host: platform more usable.

The mac address was not being initialised on the host: platform, so would change randomly. This allows it to be configured, not perhaps as good as getting an actual one, but since there are likely to be multiple hardware interfaces, that's not really practical.

The sntp component just gets the current system time on host:

The text_sensor component had some incorrect C++ declaring virtual methods;

Replace sprintf with snprintf in helpers (NB there are still plenty of places in the codebase where this needs doing.)

Add timestamps to logger output (this is done by the logging program for non-host platforms.)

Hey there @esphome/core, mind taking a look at this pull request as it has been labeled with an integration (host) you are listed as a code owner for? Thanks!

Clyde could you show me your YAML file where you use this and the VLC client. So i can us it myself as well?

Sure. All the necessary stuff is merged into the lvgl branch. Sample host.yaml:

  name_add_mac_suffix: false
  project:
    name: esphome.host
    version: "1.1"

api:
  reboot_timeout: 0s

external_components:
  - source: github://clydebarrow/esphome@lvgl
    refresh: 10min
    components: [ lvgl, font, host, vnc, sntp, time]
