[Feature Request]: Add support for logging device DPI for events

[BenHenning]

Is your feature request related to a problem? Please describe.

Events need to include the device's (unscaled) DPI as part of its log so that we can get an idea on how devices span different density formats.

Describe the solution you'd like

An integer for dpi (e.g. 320) should be logged as an event dimension (e.g. in EventBundleCreator). This should NOT be affected by display zoom.

Describe alternatives you've considered

There isn't a good alternative to get display density (one would need to manually look up the device specs).

Additional context

Needed to determine whether we need to address #360, plus it'll help with other decisions in the future.

Hi @BenHenning , I would like to work on this issue. Please assign this to me.

In the EventBundleCreator.kt file, we can have something like:
private val screenDensity by lazy { context.resources.displayMetrics.densityDpi }
and in the fillEventBundle function:
bundle.putInt( "screen_density", screenDensity )

rest all remains same.

Should I work on this issue? @BenHenning @adhiamboperes

@Tejas-67, how would you address this:

An integer for dpi (e.g. 320) should be logged as an event dimension (e.g. in EventBundleCreator). This should NOT be affected by display zoom.

[Tejas-67]

As mentioned in the previous comment, we can use resources.displayMetrics.densityDpi to get the device density.

@BenHenning, does this value need to be inclu ded for every eventlog?
