Allow support for static imports through pdex's ImportStatement.

Discontinued use of string import statement generation and migrated to pdex's ImportStatement class which can keep track of if the import is static or not. This allows static imports to be handled correctly in PDEX, JavaBuild library resoluation, and actual Java compilation step. Resolves https://github.com/processing/processing/issues/5577 and https://github.com/processing/processing4/issues/16 but only in the Processing4 branch.
