Remove DI-generated code from Kover reports

[jmartinesp]

Content

What the title says.

Motivation and context

In #6832 I realised a DI-only change was causing generated code changes that modified the coverage.

This PR mostly reverts the coverage percentage lost by not measuring some common generated classed by Metro DI.

Tests

Coverage should go up. The regexes should be specific enough to only affect classes related to Metro DI, like:

Tested devices

• Physical
• Emulator
• OS version(s): 15
