ci: Fix inclusion of NVDA lib dll/exe/pdb files in symbols artifact. (#19953)
### Summary of the issue:
The symbols artifact on CI doesn't include any of the dll/exe/pdb files
from NVDA's lib directory. This makes it almost impossible to debug
problems in NVDA C++ code unless you are using a local build. This is
particularly problematic when trying to debug nvdaHelperRemote crashes
experienced by users who aren't developers.
### Description of user facing changes:
None.
### Description of developer facing changes:
The symbols artifact on CI now includes dll/exe/pdb files from NVDA's
lib directory.
I don't think this needs a change log entry because it doesn't change
anything in NVDA itself.
### Description of development approach:
Once upon a time, NVDA had `lib\*.dll`, `lib64\*.dll`, etc. Some time
ago, the directory structure changed to `lib\x64\*.dll`,
`lib\x86\*.dll`, etc. In addition, arm64 and arm64ec libraries were
added. However, the CI symbol store creation code was never updated
accordingly. This PR updates the paths in the script.
### Testing strategy:
Checked the log output from the `Run ci/scripts/buildSymbolStore.ps1`
step on GitHub actions for this pull request. Verified that it includes
all files.
Also downloaded the artifact and checked that it contains all expected
files.
### Known issues with pull request:
None.
