WIP: [mono][tests] Enable trimming for libraries and functional tests on CI

[ivanpovazan]

This PR is currently marked as a DRAFT and is intended just for testing.

Description

The PR will be used to incrementally test enabling trimming for libraries and functional tests when targeting ios/tvos platforms on CI. To enable trimming during test builds we should set: -p:EnableAggressiveTrimming=true, however it was reported that some tests depend on not being trimmed in: #91923 which we should investigate and root/fix the failing tests accordingly.

To run a libraries test locally:

• build the runtime for a specific target:

  ./build.sh mono+libs -c Release -os ios -arch arm64

• build/run the test on a specific target (use correct Apple Team ID instead of XXXXXXXX):

  ./dotnet.sh build -c Release src/libraries/System.Runtime/tests/System.Runtime.Tests.csproj -p:TargetOS=ios -p:TargetArchitecture=arm64 -t:Test -p:MonoEnableLLVM=true -p:DevTeamProvisioning=XXXXXXXX

!IMPORTANT!

The initial commits have to be reverted as they disable the default CI triggers, which was done to avoid polluting the queues.
Incremental testing can be done by running: /azp run runtime-ioslike

Tentative plan

• Fix build on Helix configuration with trimming enabled
• Fix functional and runtime tests failures with trimming enabled
  • Fix System.Runtime.Numerics.Tests - 3 failing tests
  • Fix System.Runtime.Tests - 11 failing tests
  • Fix iOS.Device.Aot.Test
  • Fix iOS.Device.ExportManagedSymbols.Test
  • Fix any other test failures
• Measure build/trim times and compare how much we save with this change

Current state ios-arm64 with trimming

Failing work items:

• System.Runtime.Numerics.Tests - failed tests: 3 - logs
• System.Runtime.Tests - failed tests: 11 - logs
• iOS.Device.Aot.Test* - failed test: 1 - logs
• iOS.Device.ExportManagedSymbols.Test* - failed test: 1 - logs

NOTE: both functional test from above seem to run the correctly and return the expected return value, but XHarness reports XHarness exit code: 92 (TCP_CONNECTION_FAILED) marking the test as failed.

• QUESTION This should not be related to trimming, why are we experiencing that in this set up?
