perf: Moved `Authorization Control` Controller Logic To Utilities

[Abdeali099]

Moved Authorization Control controller logic to utilities

Problem:

• Authorization Control was a DocType with no fields.
• It was inheriting from TransactionBase, but there was no use of it.

Solution:

• Removed the DocType Authorization Control.
• Removed inheritance and class.
• Imported the function in usage files:

  from erpnext.utilities.authorization_control import validate_approving_authority
  

• Used the function instead of get_doc("Authorization Control"):

  - frappe.get_doc("Authorization Control").validate_approving_authority()
  + validate_approving_authority()
  

• Patch:

  execute: frappe.delete_doc_if_exists("DocType", "Authorization Control")
  

Performance Improvements:

Quotation Submission

(Local cache disabled to replicate server scenario)

Before

In [5]: %timeit d.on_submit()
953 µs ± 146 µs per loop (mean ± std. dev. of 7 runs, 1,000 loops each)

After (73% better)

In [4]: %timeit d.on_submit()
252 µs ± 5.89 µs per loop (mean ± std. dev. of 7 runs, 1,000 loops each)

• No extra DB call to get doc values during transaction submission
• No overhead of DocType meta
• No need to initialize
