av1parse: Remove duplicated check
...
The case of both strings being empty is already checked in the
helper function. No functional changes.

av1parse: Add temporal unit check when TD is absent.
...
The current manner for deciding the new temporal unit is based on
temporal delimiter(TD) OBU. We only start a new temporal unit when
the TD comes.
But some streams do not have TD at all, which makes the output "TU"
alignment fail to work. We now add check based on the relationship
between the different layers and it can successfully judge the TU edge.

av1parse: let the parse continue when MISSING_OBU_REFERENCE error.
...
Some streams may have verbose OBUs before a valid sequence header. We
should let the parse continue rather than return a error.

av1parse: Continue when we fail to detect the alignment.
...
Some streams may have problematic OBUs at the beginning, which causes
the parse fail to detect the alignment and return error. For example,
there may be verbose OBUs before a valid sequence, which should be
discarded until we meet a valid sequence. We should let the parse
continue when we meet such cases, rather than just return error.

av1parse: Set the "tu" as the default alignment.
...
The tu(temporal unit) is more widely used than the current alignment.
We now change the default alignment to tu.

av1parse: Copy the PTS and DURATION when we create data.
...
We need to create header buffers for annex b format. This kind of
buffers should inherit the PTS and DURATION from the original buffers.

codecparsers: av1parse: Add the DECODE_ONLY flag to output buffer.
...
When the alignment is ALIGN_FRAME and the output buf contains a frame
which is not to be shown, the GST_BUFFER_FLAG_DECODE_ONLY flag should
be set.

av1parse: Use descriptive profile name instead of numeric

As per AV1 specification Annex A, AV1 profiles have explicit and
