Aske Simon Christensen 23ee425de7 [vm/aot/tfa] Signature shaking for both static and instance methods ...

The existing signature shaker transforms optional and named parameters
of static and top-level methods and constructors into required
parameters whenever they are always passed.

This change improves signature shaking in a number of areas:
- Extend signature shaking to cover instance methods.
- Remove parameters which are never passed.
- Remove parameters which are not used.
- Transform signatures before unboxing, enabling transformed parameters
  to be unboxed.

TFA summaries for transformed functions are updated to stay in sync with
the program for later transformations.

Reduces instructions size of Flutter Gallery on ARM64 by 2.2%.
