Fix static p5 vector method

[Ayush4958]

Resolves #8930

Changes:

• In src/math/p5.Vector.js :- Properly bound _friendlyError & friendlyErrorsDisabled to the static Vector. Added early false after the friendly error is triggered. This prevents a secondary crash.

• Added a new unit test suite to ensure the static FES validation works.
