bundle x86 vcruntime140.dll (#20706)
Fixes #20088
### Summary of the issue:
nvda_synthDriverHost.exe depends on the x86 Visual C++ runtime, which
NVDA does not ship.
The UCRT (api-ms-win-crt-*) ships with Windows 10+, but VCRUNTIME140.dll
does not — it comes from the Visual C++ 2015–2022 Redistributable. So on
any machine without the x86 redist installed system-wide, the host fails
at image load and exits within milliseconds.
### Description of user facing changes:
Can load 32bit SAPI synths
### Description of developer facing changes:
None
### Description of development approach:
Load library. This should be installed on all dev envs through VS config
dependency `Microsoft.VisualStudio.Component.VC.Tools.x86.x64`
### Testing strategy:
- [x] Users testing from #20088 with try build: `[]()`
