processor: Add foundations for modularization of proto trace parsing
Adds structual elements to support compile-time registration of
(optional) proto trace tokenizer/parser modules.
The trace processor will instantiate enabled modules for each
TraceProcessorContext via a wrapper template, which facilitates
disabling the module at compile time (avoiding the module's
construction and dropping any calls to it).
This also avoids virtual methods, so that calling any of the module's
methods is zero overhead - they can be inlined by the compiler at
callsites directly.
