When trying to decode a file, using a stream can lead to a
pathological case where the entire file is read into memory.
If a large file is encountered, the entire file will be read
into memory and result in different types of crashes.

So instead of using a stream, use a file descriptor to prevent
this case.

Bug: 309868782

Test: Put a large file on the system. Start the files app and
Test: observe no crashes.

Some improvements in Metalava's revealed an issue with missing
`@NonNull` annotations on 2 parameters of the `BaseRecordingCanvas`'s
`drawDoubleRoundRect()` method. They are present on the overridden
method but not on the overriding method. This change adds the
missing annotations.

Not to break the apps that reads fonts.xml and add new features to
the system font customization at the same time, this CL introduces
new hidden XML file font_fallback.xml which is currently a copy of
the fonts.xml.

The fonts.xml still exists but may not contain the latest system font
settings due to compatibility problems. Application should use the
public API for accessing system installed fonts which is available
from API29.

Have Bitmap.createBitmap(sourceBitmap, ...) preserve any gainmaps if
present, transforming the gainmaps in the same way.

This addresses 2 common usages:

1) Rotating bitmaps to handle EXIF orientations
2) Bitmap.createScaledBitmap() to do "static" scaling

This allows triming of Skia font caches when an app created a lot of
transient font allocations and it knows that it won't need it anymore.
This is primarily meant for persistent processes like SystemUI to avoid
font caches taking up memory after they're not needed anymore.

So that SF could use this hint when choosing the refresh rate.
SF would only try to heuristically calculate the frame rate of a layer
when TextureView is updating. This fixes a bug where SF tries to

This creates a @hide API which only retrieves ImageInfo object without
continuing the decode of full image. It mirrors
BitmapOptions.inJustDecodeBounds behaviour and allows checking
dimensions and color space configuration of images without proceeding to
full decode (if able).

ImageDecoder.isMimeTypeSupported always returns true for
HEIF and HEIC, however, according to CDD, this support is
optional, and they are only supported when the HEVC is
supported by the device.

This change is to fix inconsistency with CDD 5.1.5, and won't
impact handhelds or TV, as HEVC is a must for them. For auto
and watch, HEVC is not supported at all. So this change is safe.
