Alex Hall 3ad2d9212e (core) Prevent rebuilding usercode for every AddColumn when importing
Summary:
Importing a file with many columns would be very slow due to expensive calls to rebuild_usercode for each added column: https://grist.slack.com/archives/C02EGJ1FUCV/p1652395747972749?thread_ts=1652388644.394419&cid=C02EGJ1FUCV

This diff suppresses rebuild_usercode temporarily while adding columns in a loop in MakeImportTransformColumns, then calls it once afterwards.

Test Plan: Manually imported a wide file repeatedly. Eventually, whehn importing a file with 300 columns, generating the preview went from taking about 100 seconds to 20 seconds.
