[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging - gpr_log
In this CL we are migrating from gRPCs own gpr logging mechanism to absl logging mechanism. The intention is to deprecate gpr_log in the future.
We have the following mapping
1. gpr_log(GPR_INFO,...) -> LOG(INFO)
2. gpr_log(GPR_ERROR,...) -> LOG(ERROR)
3. gpr_log(GPR_DEBUG,...) -> VLOG(2)
Reviewers need to check :
1. If the above mapping is correct.
2. The content of the log is as before.
gpr_log format strings did not use string_view or std::string . absl LOG accepts these. So there will be some elimination of string_view and std::string related conversions. This is expected.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging GPR_ASSERT
Replacing GPR_ASSERT with absl CHECK
These changes have been made using string replacement and regex.
Will not be replacing all instances of CHECK with CHECK_EQ , CHECK_NE etc because there are too many callsites. Only ones which are doable using very simple regex with least chance of failure will be replaced.
Given that we have 5000+ instances of GPR_ASSERT to edit, Doing it manually is too much work for both the author and reviewer.

* adding a min progress size argument to grpc_endpoint_read

* adding a static_cast
* reverting changes in tcp_posix.cc
* add missing changes to CFStreamEndpointTests.mm
The urgent argument is a platform-specific flag that leaked into the (ideally) platform-independent HTTP/2 transport layer. In an effort to clean up the cross-platform API surface, it would be helpful if we can remove this argument from the TCP Read api without losing the performance optimization that was introduced along with it (see #18240).
TCP_INQ is a socket option we added to Linux to report pending bytes
on the socket as a control message.
Using TCP_INQ we can accurately decide whether to continue read or not.
Add an urgent parameter, when we do not want to wait for EPOLLIN.

src/core. exec_ctx is now a thread_local pointer of type ExecCtx instead of
grpc_exec_ctx which is initialized whenever ExecCtx is instantiated. ExecCtx
also keeps track of the previous exec_ctx so that nesting of exec_ctx is
allowed. This means that there is only one exec_ctx being used at any
time. Also, grpc_exec_ctx_finish is called in the destructor of the
object, and the previous exec_ctx is restored to avoid breaking current
functionality. The code still explicitly calls grpc_exec_ctx_finish
because removing all such instances causes the code to break.
