Changes:

Add ETC2 texture format enums (TextureFormat::ETC2_RGB_SRGB,
ETC2_RGBA_SRGB) and component types (SNORM_FORCE_FP16, UNORM_FORCE_FP16)
Implement format lookup mappings for all ETC2 variants in
format_lookup_table.cpp
Add PixelFormat enum values and block size tables for ETC2 formats
Integrate ETC2 support into Vulkan backend with proper VkFormat mappings
Add IsOptimalEtc2Supported() device capability check
Update texture cache to handle ETC2 format conversion when needed
Add ETC2 format cases to PixelFormat formatter for logging
Improve shader environment texture handle validation with graceful
fallback for invalid handles

Fixes assertion failures for texture formats 90 and 99, enabling proper
rendering of ETC2 compressed textures using native Vulkan support.

Adds comprehensive support for ETC2 compressed texture formats (ETC2_RGB, ETC2_RGBA, ETC2_RGB_PTA) in both UNORM and SRGB variants. This addresses rendering issues in games like Hogwarts Legacy that use these formats.
