internal/postgres/symbolsearch: remove support for matching on field and method names

Symbol search on an exact symbol names that matches on field or method
names is too slow, so support is removed until performance can be
improved.

The cause is because too many symbol ids will be returned (for example,
3 rows on a exact match for "db", vs 5.2K+ when also matching on field
and method names).

For golang/go#44142
