chore(frame): remove dependency on lazy-static (#4109)

Replace the usage of lazy-static dependency by simply allocating the
object in each benchmark rather than using a static object.  There’s
really no reason to mess around and create a static object.

Furthermore, replace hex-parsing done at runtime with the use of
hex_literal.  For consistency, do that throughout the file.
