Significantly reduces the time the OSD task spends drawing elements that are completely or mostly static. The larger the element the more time savings are realized. Currently implemented support for:
- Crosshairs
- Artificial Horizon Sidebars
- Craft name
- Display name
- Stick overlay
Since the static portions are only rendered once, the static elements add no processing time to the OSD task. As an example, enabling the above elements prior to these changes results in a total rendering time of 47us. After the enhancements they take only 6us (basically the rendering phase minimum overhead). So effectively 41us are removed from the OSD task.
Opens the possibility to add large mostly static elements with no additional overhead. An example would be a camera framing element that might draw a "box" around most of the screen. Previously this would add significant processing overhead to the OSD task, but now it will have no impact.
Checks various features, modes, and OSD elements to determine if ACC is needed. Generates an arming disabled warning if ACC calibration has never been completed.
Adds `osd_distance_alarm` (defaulting to 0 for OFF) which behaves similarly to `osd_alt_alarm`. Causes the OSD distance to home element to blink if the alarm setting is exceeded.
Also added to the CMS menu for consistency with the altitude alarm.
Optionally format distance as meters/kilometers or feet/miles based on overal distance. For metric, distance will be displayed as:
0-999m: display meters
1000-9999m: display as kilometers with 2 decimals (ie. 1.23K)
10000m and above: display as kilometers with 1 decimal (ie. 10.5K)
Similar for imperial units except that will display feet up to 1 mile (5280ft), miles with 2 decimals from 1-9.99 miles, and with 1 decimal over 10 miles.
Configured with `osd_dynamic_distance_units = OFF | ON`. If off (the default) then the behavior is unchanged and the distance will be only displayed in meters or feet depending on the units selection.
There are currently no OSD font symbols for kilometers or miles so "K" and "M" are used at this time.

Removes the custom CLI commands to update or display the PID and Rate profile names. Moves the storage into the pidProfile and controlRateProfile PG's.
Names can now be set with:
set profile_name = NAME
set rate_profile_name = NAME
Also added profile name display to the profile and rate CMS menus.
