This change adds "." and "-" support for DLL filenames in "//sys". Supporting "." requires a change in how mkwinsyscall handles the "= <filename>.<function>" syntax. Instead of assuming that only one "." can appear in this string, now mkwinsyscall assumes that any additional "." belongs to the filename. Supporting "." also requires changing how Go identifiers are created for each DLL. This change also allows mkwinsyscall to support "-". When creating a Go identifier, "." and "-" in the DLL filename are replaced with "_". Otherwise, mkwinsyscall would produce invalid Go code, causing "format.Source" to fail. Includes a test for the new behavior. There aren't yet any cases where this code is executed while generating the x/sys/windows syscalls. The syscalls "SetSocketMediaStreamingMode" from "windows.networking.dll" and "WslRegisterDistribution" from "api-ms-win-wsl-api-l1-1-0.dll" can be successfully called using this change, but these syscalls have no known use in Go so they are not included in this change.
