chore(tracer): remove asm properties from the tracer class

[mabdinur]

Description

Removes the following tracer fields and replaces all usages with the corresponding asm_config:

• Tracer._asm_enabled
• Tracer._iast_enabled
• Tracer._appsec_standalone_enabled

Next steps:

• Remove all asm, profiling, and serverless specific logic from ddtrace/_trace/tracer.py.
  • Define a product level configure methods
  • Introduce product level processors and then product specific logic.
  • Deprecate calling tracing.configure(....) for non tracing features.

Motivation

• Decouples asm configurations from tracing
• Avoids storing duplicate references for global configurations. Ideally global configurations should have once source of truth. This will help simplify remote configuration.
