[TT-9551] Fix scope issues

[titpetric]

Description

This addresses a few scope / compilation issues.

• It removes a deprecated https://pkg.go.dev/golang.org/x/net/context
• It aliases use of stdlib apis via internal packages (1 import from gw package, no fragmentation)
• The coprocess_api.go imports C, put it behind a cgo build tag
• Aliases use of text/template and html/template (scope differentiation, within the package scope both of those are named template, aliasing makes code non-conflicting on itself).
• Fixes a test case to pass sonarcloud (asserting error return in test)

The deprecated context package is coming from the msgpack.v2 dependency (go mod why). Investigate bumping the dependency, or replacing it with an up to date one (out of scope).
