[Lambda] Replace Facade with No-Op if trace header is missing data

[majanjua-amzn]

To support Root Lambda PassThrough, we want to have a no-op segment when PassThrough mode is enabled to allow for SDK to have its functionalities disabled for the given segment. The following tests were done using two lambda functions, A and B, where A calls B.

Lambda A PassThrough calling Prod Lambda B Active:

• A: Root=1-665a0c0c-2420a39e4fca953752e2e9f4;Lineage=061379e8:0
• B: Root=1-665a0c0c-2420a39e4fca953752e2e9f4;Parent=8c885bca7ccc2033;Sampled=1;Lineage=061379e8:0|cbc84ad3:0

Lambda A Active calling Prod Lambda B Active:

• A: Root=1-665a39a0-7e53f00f3b1da8ad70666729;Parent=ce7fe8bbc2783986;Sampled=1;Lineage=061379e8:0
• B: Root=1-665a39a0-7e53f00f3b1da8ad70666729;Parent=e80ec591cab089eb;Sampled=1;Lineage=061379e8:0|cbc84ad3:0
