DynamicTablesPkg/AmlLib: Fix serialization buffer size handling
AmlSerializeTree uses a reversed buffer size comparison. As a result, it
returns success without serializing when the buffer is larger than needed
and attempts serialization when the buffer is too small.
Return EFI_BUFFER_TOO_SMALL when Buffer is NULL or the supplied buffer is
too small, and always report the required size. Update
AmlSerializeDefinitionBlock to handle the expected size query status.

DynamicTablesPkg/AmlLib: Fix fixed argument bounds check
AmlSetFixedArgument() accepts an index equal to the fixed argument count.
The count is an exclusive upper bound, so this permits an out-of-bounds
write to the FixedArgs array.
Require the index to be strictly less than the fixed argument count.

DynamicTablesPkg/AmlLib: Fix data node cleanup leak
AmlCreateDataNode() calls AmlDeleteDataNode() when buffer allocation
fails. However, AmlDeleteDataNode() rejects a NULL buffer and returns
without freeing the data node, leaking the node allocation.
Allow AmlDeleteDataNode() to handle a NULL buffer and always free the
data node.

DynamicTablesPkg/AmlLib: Fix root node cleanup leak
AmlCreateRootNode() calls AmlDeleteRootNode() when SDT header
allocation fails. However, AmlDeleteRootNode() rejects a NULL header
and returns without freeing the root node, leaking the node allocation.
Allow AmlDeleteRootNode() to handle a NULL SDT header and always free
the root node.
