go: Upgrade to 1.18

1.18 is a major release brings in long awaited new features e.g.
generics, fuzzing

Detailed list is here [1]

Drop patches to manipulate multiword CC/CXX as go has fixed it
differently [2]

Drop cgo portion of patch to hack hash generation logic
either we should find a way to not use it or redo it,
in current form its not upstreamable and its
altering core features of go compiler, it can not be maintained as is

Do not emit linkinfo into the actionID

Drop ignoring CVE-2021-29923 its already addressed in go >= 1.17

+Subject: [PATCH] cmd/go: make content-based hash generation less pedantic
+
+Go 1.10's build tool now uses content-based hashes to
+determine when something should be built or re-built.
+This same mechanism is used to maintain a built-artifact
+cache for speeding up builds.
+
+However, the hashes it generates include information that
+doesn't work well with OE, nor with using a shared runtime
+library.
+
+First, it embeds path names to source files, unless
+building within GOROOT.  This prevents the building
+of a package in GOPATH for later staging into GOROOT.
+
+This patch adds support for the environment variable
+GOPATH_OMIT_IN_ACTIONID.  If present, path name
+embedding is disabled.

-
-Upstream-Status: Inappropriate [OE specific]
-
-Go 1.10's build tool now uses content-based hashes to
-determine when something should be built or re-built.
-This same mechanism is used to maintain a built-artifact
-cache for speeding up builds.
-
-However, the hashes it generates include information that
-doesn't work well with OE, nor with using a shared runtime
-library.
-
-First, it embeds path names to source files, unless
-building within GOROOT.  This prevents the building
-of a package in GOPATH for later staging into GOROOT.
-
-This patch adds support for the environment variable
-GOPATH_OMIT_IN_ACTIONID.  If present, path name
-embedding is disabled.
-
-Second, if cgo is enabled, the build ID for cgo-related
-packages will include the current value of the environment
-variables for invoking the compiler (CC, CXX, FC) and
-any CGO_xxFLAGS variables.  Only if the settings used
-during a compilation exactly match, character for character,
-the values used for compiling runtime/cgo or any other
-cgo-enabled package being imported, will the tool
-decide that the imported package is up-to-date.
-
-This is done to help ensure correctness, but is overly
-simplistic and effectively prevents the reuse of built
-artifacts that use cgo (or shared runtime, which includes
-runtime/cgo).
-
-This patch filters out all compiler flags except those
-beginning with '-m'.  The default behavior can be restored
-by setting the CGO_PEDANTIC environment variable.
-
-Adapted to Go 1.13 from patches originally submitted to
-the meta/recipes-devtools/go tree by
-Matt Madison <matt@madison.systems>.
