Bump the max size of four binder caches 

This change increases the maximum size of selected binder caches.
This table lists the module, the API, the old cache size, and the new
cache size.  Note that the new cache size is only needed during
system boot: the steady-state cache size is much smaller.

 * IPackageManager      getPackagesForUid      32    1024
 * IPlatformCompat      isChangeEnabledBy_X    64    2048
 * IPackageManager      getApplicationInfo     32    2048
 * IPackageManager      getPackageInfo         64    2048

The IPlatformCompat cache is a single cache for two different APIs:
isChangeEnabledByPackageName() and isChangeEnabledByUid().

Flag: EXEMPT bug_fix
Bug: 346346313
Test: Boot the phone and observe the number of caches that have
      overflowed.
