haroonq b950598d11 Various fixes to support gcc compilation. (#9323 )

* Add missing includes.

* Add parenthesis around operators to suppress compiler warning.

* Remove duplicate definition of is_supported_aux_t.

* Explicitly create descriptions.

* Remove usage of anonymous struct with non-trivially constructible members.

This is an error on some compilers (e.g. gcc).

* Remove unnecessary rvalue-reference on pointer type.

* Explicitly construct SamplerParams to suppress compiler warnings.

* Place attribute specifier before declaration.

* Remove usage of anonymous struct with a non-trivially constructible member.

Replace the `array` union member with an `operator[]` to provide similar
functionality.

Some compilers (e.g. gcc) do not support this non-standard use-case.

* Use same warning settings as main filament project.

Description

gltfio is a loader library that consumes gltf or glb content and produces Filament objects. For usage details, see the docstring for AssetLoader.

gltfio has two plug-in interfaces, TextureProvider and MaterialProvider. Filament ships with several ready-to-go implementations described below.

MaterialProvider creates Filament materials in response to certain glTF requirements.
- UbershaderProvider loads pre-built materials.
- JitShaderProvider builds materials at run time using the filamat library.
TextureProvider creates and populates Filament Texture objects.
- StbProvider uses the STB library to read PNG and JPEG files.
- Ktx2Provider uses the BasisU library to read KTX2 files.

UbershaderProvider

UbershaderProvider is a ready-to-go implementation of the MaterialProvider interface that should be used in applications that need fast startup times. There is no material compilation that occurs at run time, but the shaders might be relatively large and complex.

At load time, the ubershader loader consumes an ubershader archive which is a precompiled set of materials bundled with formal descriptions of the glTF features that they support.

The uberz command line tool consumes a list of .spec and .filamat files and produces a single .uberz file. For details on these two file formats, see the README in libs/uberz.
