add SRM 1.3 toolchains

[hgy59]

Description

• add toolchains extracted from toolkit from Synology downloads
• add SRM 1.3 to build matrix
• hawkeye is an early release and seems incorrect (router model WRX560 not yet released)

Fixes #5402

Remarks

• hawkey is used by a not yet released router model (WRX560) and is suggested not to work

  • the CPU should be aarch64 like cypress but the toolchain file hawkeye-1.3 is binary the same as dakota-1.3 an armv7

• some kernel- and glibc-versions have to be veryfied - those are not documented in the toolkit (content/name) like all DSM toolkits.

• the toolchains are availabel under https://github.com/SynoCommunity/spksrc/releases/tag/toolchains/srm1.3
  it is documented there how the toolchains were extracted from the toolkit files
