SI-7501 Pickler: owner adjustment for param syms in annotation args

Pickling of trees within annotation arguments led to an unfortunate
situation: the MethodType of a symbol contained a value parameter
symbol that was pickled as though it were owned by the enclosing
class (the root symbol of the pickle.)

Under separate compilation, this would appear as a member of that
class.

Anyone using `@deprecatedName('oldName)` was exposed to this problem,
as the argument expands to `Symbol.apply("oldName")`.

This commit extends some similar treatment of local type parameters
to also consider value parameters.
