Include debug symbols for all distributed binaries

[magreenblatt]

Original report by me.

---

We currently only ship debug symbols for the libcef binary. We should also ship symbols for the other binaries that we distribute (cef_sandbox, chrome_elf, libEGL, libGLESv2).

Windows (M127 Release x64) has the following:

chrome_elf.dll.pdb
dxcompiler.dll.pdb
eventlog_provider.dll.pdb
libcef.dll.pdb
libEGL.dll.pdb
libGLESv2.dll.pdb
VkICD_mock_icd.dll.pdb
VkLayer_khronos_validation.dll.pdb
vk_swiftshader.dll.pdb
vulkan-1.dll.pdb

Note that we don't currently ship all of these DLLs. Google Chrome Beta (127.0.6533.26) includes the following DLLs:

chrome.dll
chrome_elf.dll
chrome_wer.dll
d3dcompiler_47.dll
dxcompiler.dll
dxil.dll
eventlog_provider.dll
libEGL.dll
libGLESv2.dll
mojo_core.dll
optimization_guide_internal.dll
vk_swiftshader.dll
vulkan-1.dll

About the DLLs that currently (at M127) ship with Google Chrome but not CEF:

• eventlog_provider.dll supports logging to Windows Event Log, see https://crbug.com/40482646
• chrome_wer.dll supports custom Windows Error Reporting (WER), see https://crrev.com/6d61c62f7b
• mojo_core.dll is a shared mojo runtime (current usage unclear), see https://crbug.com/40582133
• optimization_guide_internal.dll supports the remote Chrome Optimization Guide Service, see docs
