Currently, ExtractAPI provides availability information for all
platforms within a given domain. With this change, we narrow down the
output to include availability details only for the specified target
platform, so users can generate the symbol graph with only the
availability information they need, omitting information of the other
platforms.
This change reverts the functionality introduced in
[`57c9780`](https://github.com/llvm/llvm-project/commit/57c9780).

Other implementations of the symbol graph format use zero-based indices
for source locations, which causes problems when combined with clang's
current one-based indices. This commit sets ExtractAPI's symbol graph
output to use zero-based indices to align with other implementations.

This Patch gives ExtractAPI the ability to emit correct availability information for symbols marked as unavailable on a specific platform ( PR#60954 )

Currently ExtractAPI only emits availability information for the
current platform. This makes it easy for clients to get all availability
information for a given symbol in one invocation as opposed to having to invoke
clang once per-platform and then merge the symbol-graphs.
