[Binary] Make the OffloadingImage type own the memory
Summary:
The OffloadingBinary uses a convenience struct to help manage the memory
that will be serialized using the binary format. This currently uses a
reference to an existing buffer, but this should own the memory instead
so it is easier to work with seeing as its only current use requires
saving the buffer anyway.

[Binary] Promote OffloadBinary to inherit from Binary
We use the `OffloadBinary` to create binary images of offloading files
and their corresonding metadata. This patch changes this to inherit from
the base `Binary` class. This allows us to create and insepect these
more generically. This patch includes all the necessary glue to
implement this as a new binary format, along with added the magic bytes
we use to distinguish the offloading binary to the `file_magic`
implementation.

[Object] Add binary format for bundling offloading metadata
We need to embed certain metadata along with a binary image when we wish
to perform a device-linking job on it. Currently this metadata was
embedded in the section name of the data itself. This worked, but made
adding new metadata very difficult and didn't work if the user did any
sort of section linking.
This patch introduces a custom binary format for bundling offloading
metadata with a device object file. This binary format is fundamentally
a simple string map table with some additional data and an embedded
image. I decided to use a custom format rather than using an existing
format (ELF, JSON, etc) because of the specialty use-case of this. We
need a simple binary format that can be concatenated without requiring
other external dependencies.
This extension will make it easier to extend the linker wrapper's
capabilties with whatever data is necessary. Eventually this will allow
us to remove all the external arguments passed to the linker wrapper and
embed it directly in the host's linker so device linking behaves exactly
like host linking.
