Content Launcher feature map shows up as indexes instead of bitmask

[andy31415]

Definition of

<bitmap name="Feature" type="bitmap32">
     <cluster code="0x050a"/>
     <field name="ContentSearch" mask="0x1"/>
     <field name="URLPlayback" mask="0x2"/>
     <field name="AdvancedSeek" mask="0x3"/>
     <field name="TextTracks" mask="0x4"/>
     <field name="AudioTracks" mask="0x5"/>
   </bitmap>

is wrong because masks should be 0x01, 0x02, 0x04, 0x08, 0x10, ... instead of using indexes. This prevented us from migrating to feature bits for these features.

If we use these, there may be sideffects. Need to update the data type and validate if there are any sideffects in code (that thinks these are indexes instead of bitmasks).

Looks like the buggy XML was added in #30691 @lazarkov @hawk248 @Brian-Resideo

These are not actually used in the code today, but this should be fixed to prevent future issues in case developers reference the output from these.

They're shipped in the Android and Python APIs, no? (And Darwin, but we made sure to not expose this to API consumers so far....)
