[Port v2int 3.0] Rename TelemetryContext::SetAll to SetMultiple

[agarwal-navin]

Porting fa58a17 to release/v2int/3.0 as this is a breaking change. runtime-utils version 2.0.0-internal.3.0 running with runtime-definitions version 2.0.0-internal.3.2+ will not work because this change went into 2.0.0-internal.3.2.

#14070 added a setAll method to TelemetryContext that can be used to set mutliple values to the telemety context. As per #14153 (comment), renaming the method to setMultiple since its more inline with what it does.
