Fix: Obtain aom_image metadata on decode

Fixes reported issues oss-fuzz:19118, oss-fuzz:19157 and decoder
conformance test vector failure.

Summary:
- Added aom_img_get_metadata() function so user can obtain metadata
associated with an aom_image.
- Added aom_img_num_metadata() function so user can get the number of
metadata blocks associated with an aom_image.
- Added image metadata array to AV1Decoder so it can be obtained during
decoding process.
- Implemented read_metadata_itut_t35() to parse ITU-T T.35 metadata from
stream to metadata array.
- Added necessary tests for these new functions.
- Only ITU-T T.35 metadata decoding is implemented in this CL.
