[llvm] [lldb][bazel] Add PlatformWasm plugin library to the Bazel overlay (PR #209749)

[David Young via llvm-commits]

https://github.com/youngd007 created https://github.com/llvm/llvm-project/pull/209749

Adds the PluginPlatformWasm cc_library plus its PlatformWasmProperties gentbl_cc_library (settings .td, modeled on PlatformQemuUserProperties) to the lldb Bazel overlay. Deps mirror
source/Plugins/Platform/WebAssembly/CMakeLists.txt (lldbCore, lldbHost, lldbTarget, lldbUtility, Support) plus the :PluginPlatformGDB and :PluginProcessWasm plugin deps its GDB-remote/Web-Inspector sources use. The library is intentionally left out of DEFAULT_PLUGINS.

bazel rule assisted with: claude

Can confirm this library will convert to BUCK internally at Meta and build with buck2 where we do have in the default plugin list. I left it out here, unless there's a desire to add it in.
