[azsdk-cli] [TypeSpec Authoring]Scope azsdk_customized_code_update Customization tool

azsdk_customized_code_update customization tool will support three edit scope, each edit scope will apply different customization and verification and required repo environment.

** Three edit-scope**
customization tool will handle customization request this in three edit-scope modes:
- edit-scope = tsp: allow edits to typespec only, with no code customization, so package-path is not required.
- edit-scope = customizeCode: allow edits to sdk code only, with no typespec changes, so tsp-project-path is not required.
- edit-scope = all: require both package-path and tsp-project-path.

**Action, repo for each edit scope**
the details about repo required, customization task, and the verification mechanism to use after applying the customization for
Stage | Repo | scope | customization | verification | fallback
-- | -- | -- | -- | -- | --
local dev | spec repo + SDK repo | all/ specInput | typespec customization, SDK code customization | typespec compileSDK re-generateSDK build | code customization
Spec PR | Spec repo | specInput | Typespec customization | typespec compile | No
SDK PR | SDK repo | CustomCode | SDK code customization | SDK build | No

To apply scoped customization, the whole customization flow will be:
