Draft: Add ad-hoc indexing Feature Flag

Pam Artiagarequested to merge
pam/add-ff-for-adhoc-indexing into master

What does this MR do and why?

We recently added the capability to trigger ad-hoc indexing when the semantic_code_search MCP tool is invoked (see Issue | MR).

Currently, the only way to toggle ad-hoc indexing (ie, if there are issues during rollout or testing) is to toggle the semantic_code_search MCP tool

This MR adds a gitlab_com_derisk feature flag. This should allow us to disable ad-hoc indexing without disabling the semantic_code_search tool. This can be useful once we are rolling out to all namespaces, and some projects already have Code Embeddings, but we want to temporarily disable ad-hoc indexing for other projects due to problems.
