Remove validated ORT core patches

[tzuhsuanwei]

Summary

This PR removes ORT-core patches 0002, 0004, and 0005 so the QNN plugin can build against a cleaner, unmodified upstream ORT source tree.

Patch 0002 previously changed ORT core solely to prevent the model runner from executing three QNN HTP RoiAlign test directories. The upstream plugin runner accepts a suite directory but has no per-case skip argument. Removing 0002 without replacement would make the normal full node-suite workflow execute est_roialign_mode_max, which is currently unsupported on QNN HTP and returns Not implemented.

Therefore this PR moves that test-selection policy out of ORT core and into a QNN-owned Python filter. Windows and Linux launchers call the filter before invoking the upstream plugin runner; Appium/QDC applies it before uploading the node suite to the device. The runner receives a temporary filtered suite, so ORT itself remains pristine and no longer needs a QNN-specific skip patch. This preserves the prior test workflow while keeping the ORT patch chain clean.

• Remove 0002, 0004, and 0005 from the FetchContent patch chain and delete their patch files.
• Re-home 0002's former RoiAlign exclusions in the QNN test harness, not ORT core.

Final patch disposition

Patch	Decision	Evidence / removal gate
0001 plugin EP runner	Keep	QNN still depends on the local plugin-EP runner implementation.
0002 RoiAlign HTP exclusions	Remove	Upstream runner has no individual-case skip CLI. QNN filter explicitly excludes the three former cases before runner invocation and logs reasons.
0003 arm64ReproDir	Keep	Upstream arm64x.cmake unconditionally overwrites arm64ReproDir; outer QNN CMake cannot fix it after ORT configures. Keep until upstream supplies a cache variable/override hook and ARM64X repro paths validate.
0004 monolithic LSTM option	Remove	Plugin runner forwards arbitrary key/value provider options; explicit enumeration is redundant.
0005 MSVC C4875	Remove	Pinned ORT v1.29 contains upstream GSL C4875 root-cause fix.
0006	No action	No patch file or application reference exists.
0007 Android QNN_LIB_FILES copy	Keep	Android Java/AAR path can still invoke cmake -E copy with an empty source list.
0008 rank-5/6 HandleReshapeSplit	Keep	QNN SpaceToDepth/ChannelShuffle fusions need hardening for the optimizer-produced form.

Validation

• Fresh ARM64 source build after moving prior build tree aside.
• Fresh ort_core patch stamp omits 0002; fresh ORT TestCase.cc/main.cc contain no RoiAlign exclusions.
• Fresh ARM64 runner and matching DLLs deployed to V81.
• V81 HTP run with backend_type|htp and htp_arch|81: Models 1, Succeeded 1, Not implemented 0, Failed 0.
• Filter staging suite excludes test_roialign_aligned_false, test_roialign_aligned_true, and test_roialign_mode_max while retaining test_abs.
• Python 3.8 filter smoke test passed; Windows launcher PowerShell syntax passed.
• Repository lint was run before the PR reduction/reinstatement; this PR's restored filter code is the same validated implementation.
