1. Updated xtask scripts to generated bindings for MIPS
alongside other architectures.
2. Updated `aya-obj/src/generated/mod.rs` and `bpf/aya-bpf-bindings/src/lib.rs` to
use the mips bindings.
3. Update `write_to_file` method to create parent directories if they
don't exist already.
- Set the version number of `aya-obj` to `0.1.0`.
- Update the description of the `aya-obj` crate.
- Add a section in README and rustdoc warning about the unstable API.
This commit adds documentation on how program names are parsed from
section names, as is used by `aya_obj::Object.programs` as HashMap keys,
and updates the examples into using program names.
The crate has few libstd dependencies. Since it should be platform-
independent in principle, making it no_std like the object crate would
seem reasonable.
However, the feature `error_in_core` is not yet stabilized, and the
thiserror crate currently offers no no_std support. When the feature
no_std is selected, we enable the `error_in_core` feature, switch to
thiserror-core and replace the HashMap with the one in hashbrown.
To split the crate into two, several changes were made:
1. Most `pub(crate)` are now `pub` to allow access from Aya;
2. Parts of BpfError are merged into, for example, RelocationError;
3. BTF part of Features is moved into the new crate;
4. `#![deny(missing_docs)]` is removed temporarily;
5. Some other code gets moved into the new crate, mainly:
- aya::{bpf_map_def, BtfMapDef, PinningType},
- aya::programs::{CgroupSock*AttachType},
The new crate is currenly allowing missing_docs. Member visibility
will be adjusted later to minimize exposure of implementation details.

Aya::obj depends on bindgen generated files, and we start
by migrating bindgen generated files.
This commit adds the new aya-obj crate to the workplace
and migrates generated files into the crate. We use core
instead of std in an effort to make the final crate no_std.
Bindgen was run against libbpf v1.0.1.
