[v7] Type imports using full path file reference and no .d extension causes parcel build failure

[ifsimicoded]

Context

Blocking a release? (y/n): N

Regression issue? (y/n): N

Priority: P2/P3 - doesn't align with typical development infrastructure, but can be worked around easily. Maybe this reflects poorly on our code quality / repo setup.

Steps to reproduce the issue

1. Use full path import to import types from type files without using the type modifier (this is not a current requirement in the repo)
2. TS check is ok. Build / serve fails with parcel resolver unable to find the file.
