[MSE] Avoid copies during AAC and IAMF bitstream conversion.

The bitstream conversion path for AAC, IAMF worked by copying the
packet buffer into a std::vector then inserting a bunch of data
at the front of the vector, then using an external memory adapter
to carry the vector around.

We can avoid an initialization, copy, and resize by switching to
a base::HeapArray that's passed into the StreamParserBuffer.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
