fix GLES/GL shared contexts define, move serialization instead

[cscd98]

Guidelines

1. Rebase before opening a pull request
2. If you are sending several unrelated fixes or features, use a branch and a separate pull request for each
3. If possible try squashing everything in a single commit. This is particularly beneficial in the case of feature merges since it allows easy bisecting when a problem arises
4. RetroArch codebase follows C89 coding rules for portability across many old platforms check using C89_BUILD=1

Description

This PR #19161 changed the ID for RETRO_ENVIRONMENT_SET_HW_SHARED_CONTEXT and RETRO_ENVIRONMENT_SET_SERIALIZATION_QUIRKS, however in doing so all cores that supported GL/GLES shared contexts e.g. dolphin were broken.

Lets move RETRO_ENVIRONMENT_SET_SERIALIZATION_QUIRKS instead as its less important.
