[NFC][LLDB][BoundsSatety] Add `InstrumentationRuntime::MatchAllModules` (#166001)

This adds a virtual method that allows `InstrumentationRuntime` sub
classes to match against all modules rather than just a library that
matches a particular regex. When the implementation returns true
`GetPatternForRuntimeLibrary()` is ignored and all modules are iterated
over. The default implementation returns false which was the previous
behavior which uses `GetPatternForRuntimeLibrary()` to only match a
particular runtime library.

The intended use case here is for implementing an
`InstrumentationRuntime` where the runtime library of interest can have
multiple implementations and whose name is not known ahead of time.

The concrete use case here is for a `InstrumentationRuntime` plugin for
implementations of the `-fbounds-safety` soft-trap runtime which can
have multiple different implementations and so the module containing the
runtime functions isn't known ahead of time. This plug-in will be
upstreamed as part of the process of upstreaming `-fbounds-safety`.

An alternative to this would be for the `GetPatternForRuntimeLibrary()`
function to return a regex that matches everything. While that
technically works this new API more clearly indicates in the intent. We
probably also save a little perf by not executing the regex match for
every loaded module but I have not measured this.
