ssize_t is a GNU extension and is not available on Windows or MacOS.
Instead, we use intptr_t which should be effectively equivalent and is
part of the C standard. This should fix the Windows and Mac OS builds.

There are certain advantages to using uint8_t internally such as
well-defined arithmetic on all platforms. However, interfaces that
work in terms of raw data should use a void* type.

These helpers not only call blob_reserve_bytes but also make sure that
the blob is properly aligned as if blob_write_* were called.

Despite the name, it could only be used if you immediately wrote to the
pointer. Noboby was using it outside of one test, so clearly this
behavior wasn't that useful. Instead, make it return an offset into the
data buffer so that the result isn't invalidated if you later write to
the blob. In conjunction with blob_overwrite_bytes(), this will be
useful for leaving a placeholder and then filling it in later, which
we'll need to do for handling phi nodes when serializing NIR.

These can be used to easily count up the number of bytes that will be
required by "writing" it into the NULL blob.

There's no reason why that tiny bit of memory needs to be on the heap.
We always put blob_reader on the stack, so why not do the same with the
writable blob.

We're going to want to use the blob for Vulkan pipeline caching so it
makes sense to have it in libcompiler not libglsl.
